== Introduction ==
 
== Introduction ==
'''Note on Ubuntu versions:''' This guide is for installing Firefox 2.x on Ubuntu 5.10 (codename Breezy Badger) and 6.06 LTS (codename Dapper Drake). Firefox 2 is included in the default Ubuntu 6.10 (codename Edgy Eft) release, if you are using 6.10 you can install it in the standard manner described in [[UbuntuHelp:InstallingSoftware|InstallingSoftware]] and do not need this guide.
+
When a new version of Firefox comes out, there is some delay until it can be downloaded and run.  This page will explain how to install Firefox as soon as possible.
'''Warning:''' If you use this guide, '''do not remove the Ubuntu version of Firefox.''' Doing so will break the following packages: Yelp (help viewer), Epiphany, Gnome-app-install (Add Applications), Liferea, Blam and any application requiring the Gecko rendering engine.
+
The ''Check For Updates'' link in Firefox is disabled in Ubuntu. Firefox should only be updated through the [[UbuntuHelp:InstallingSoftware|package-management system]].
== Installing Firefox from Mozilla.com ==
+
== Instructions for the impatient ==
For some reason, the build of Firefox from [http://www.getfirefox.com/ Mozilla] is significantly faster than the default Ubuntu one.
+
'''Low difficulty, high safety''': these packages are maintained and fully tested by the Ubuntu Project
=== Notes ===
+
* Hardy - Karmic: Coming Soon
* You will no longer get automatic updates for Firefox through the repositories (but Firefox itself has a built into auto-updater, see below for how that works).
+
{|border="1" cellspacing="0"
* The Totem video plugin doesn't seem to work with Firefox 2.x. You may want to install package <code><nowiki>mozilla-mplayer</nowiki></code> instead before you start.
+
|https://help.ubuntu.com/community/IconsPage?action=AttachFile&do=get&target=IconWarning3.png||This section explains how to install packages that ''have not been fully tested''. If you encounter bugs, please file against the [https://bugs.launchpad.net/ubuntu/+source/firefox firefox] package and tag PPA.
* You need the package <code><nowiki>libstdc++5</nowiki></code> installed. If you need help look at the [[UbuntuHelp:InstallingSoftware|InstallingSoftware]] page.
+
|}
* This is for i386. If you are on amd64, there are some specific tips in [[UbuntuWiki:FirefoxAMD64FlashJava|FirefoxAMD64FlashJava]]
+
=== Firefox-stable channel ===
* If you are using scim-1.0.2 as your input method platform, Firefox will crash on startup. You may manually build Firefox to make both of them work. See [[UbuntuHelp:SCIM|SCIM]] and [[UbuntuHelp:CompileFirefoxNewVersion|CompileFirefoxNewVersion]] for more information. If you don't know what SCIM is, you probably aren't using it - it is used for some non-English character sets only.
+
'''Medium difficulty, medium safety''': Firefox 3.6 completely replaces previous versions of Firefox and incompatibilities may arise.
* To get the Flash plugin working properly, you may have to add "export XLIB_SKIP_ARGB_VISUALS=1" to the Firefox launching script or see the [[UbuntuHelp:RestrictedFormats|RestrictedFormats]] page.
+
Mozilla team made Firefox 3.6 available to Ubuntu community for testing.   
* Middle clicks on tabs work differently on the Linux builds due to the middle click button being used as a paste text shortcut. Type <code><nowiki>about:config</nowiki></code> in the address bar and set the <code><nowiki>middlemouse.contentLoadURL</nowiki></code> value to <code><nowiki>False</nowiki></code>. This fixes the issue and is the default for Firefox 2 Linux builds.
+
<ol><li>Go to the [https://launchpad.net/~mozillateam/+archive/firefox-stable mozilla-team firefox-stable personal package archive].
* The Mozilla build will ''not'' be compiled from source. Rather, it comes with all libraries and system information and can run after being extracted. This guide will help you place it in the proper directory and with the correct paths.
+
</li><li>Karmic 9.10 or later: Add '''ppa:mozillateam/firefox-stable''' to your system's Software Sources.
=== Automated Install of the Latest Firefox ===
+
</li><li>Jaunty 9.04 or earlier: Follow the [https://edge.launchpad.net/+help/soyuz/ppa-sources-list.html official instructions] on how to use software from a PPA.
The [http://ubuntuzilla.sourceforge.net Ubuntuzilla] project maintains an automated script that backs up your Firefox profile, locates and downloads the latest Firefox release, allows you to select a locale, verifies download integrity with Mozilla Software Releases GPG signature, and installs Firefox into /opt/firefox with all the proper symlinks in /usr/bin.
+
</li><li>Install the package for the new version of Firefox (e.g. package name is ''firefox'')
In other words, it does everything this step-by-step tutorial does and more... but with less copying and pasting and more error checking.
+
</li><li>[[UbuntuWiki:MozillaTeam/Bugs|Report|any bugs]] that you experience - especially anything that previously worked, then stops working</li></ol>
Detailed usage instructions and more information are available on [http://ubuntuzilla.sourceforge.net Ubuntuzilla] project site. 64-bit users, you'll need some extra 32-bit compatibility packages ([http://ubuntuzilla.wiki.sourceforge.net/#usersof64bitubuntu see this note for 64 bit users]).
+
If you run into any problems with this script, or have feature requests, comments, suggestions, please feel free to post on the [http://ubuntuforums.org/forumdisplay.php?f=251 Ubuntuzilla project forum], now officially hosted on the Ubuntu forums in the [http://ubuntuforums.org/forumdisplay.php?f=46 3rd Party Projects] area.
+
=== Manual Install ===
+
* First, back up your bookmarks and settings:
+
<pre><nowiki>
+
cd ~/.mozilla/firefox/*.default
+
mkdir ~/Desktop/ffsettings
+
cp bookmarks.html cert8.db cookies.txt formhistory.dat hostperm.1 key3.db signons.txt history.dat  mimeTypes.rdf ~/Desktop/ffsettings
+
</nowiki></pre>
+
* Download Firefox from the [http://www.getfirefox.com Firefox] website, and change to the directory you downloaded it to.
+
* Install it to /opt/firefox:
+
<pre><nowiki>
+
# extract the tar file into /opt (you should make sure /opt already exists)
+
sudo tar xzvf firefox-2.0.0.1.tar.gz -C /opt
+
# remove the package if you no longer require it
+
rm firefox-2.0.0.1.tar.gz
+
</nowiki></pre>
+
* Link to your plugins and remove <code><nowiki>totem-mozilla</nowiki></code> as it doesn't seem to work with Firefox 1.5.x or 2.x:
+
<pre><nowiki>
+
  sudo mv /opt/firefox/plugins /opt/firefox/plugins.bak
+
sudo ln -s /usr/lib/firefox/plugins /opt/firefox/plugins
+
sudo rm /usr/lib/firefox/plugins/libtotem_mozilla.*
+
</nowiki></pre>
+
* Change to your home directory, and rename your old profile, leaving it as a backup (using the existing profile may cause problems with Firefox 2.x):
+
<pre><nowiki>
+
cd
+
mv ~/.mozilla/firefox ~/.mozilla/firefox1.x.ubuntu
+
</nowiki></pre>
+
* To ensure it is used as the default version, modify the symbolic link in /usr/bin:
+
<pre><nowiki>
+
# First, /usr/bin/firefox
+
sudo dpkg-divert --divert /usr/bin/firefox.ubuntu --rename /usr/bin/firefox
+
sudo ln -s /opt/firefox/firefox /usr/bin/firefox
+
# Then, /usr/bin/mozilla-firefox, used as the default gnome browser
+
sudo dpkg-divert --divert /usr/bin/mozilla-firefox.ubuntu --rename /usr/bin/mozilla-firefox
+
sudo ln -s /opt/firefox/firefox /usr/bin/mozilla-firefox
+
</nowiki></pre>
+
The dpkg-divert command will move the original system-wide /usr/bin/firefox to a new name.
+
The ln command will place a symlink to the newly installed Firefox in /usr/bin.
+
* Try it out: :-)
+
<pre><nowiki>
+
firefox
+
</nowiki></pre>
+
*Running Firefox in terminal may cause errors to show but don't worry about that, it will still work once Firefox is restarted. The reason for these errors is because Firefox 2 is checking for updates, which is not abnormal activity. Also, running this command make take a some time to execute, please be patient.
+
*Restore your old data:
+
<pre><nowiki>
+
cd ~/Desktop/ffsettings
+
mv * ~/.mozilla/firefox/*.default
+
</nowiki></pre>
+
*Restore your search plugins:
+
<pre><nowiki>
+
sudo cp -i --reply=no /usr/lib/mozilla-firefox/searchplugins/* /opt/firefox/searchplugins/
+
sudo cp -i --reply=no ~/.mozilla/firefox1.x.ubuntu/*.default/search/* /opt/firefox/searchplugins/
+
</nowiki></pre>
+
Some users are having a problem with the <code><nowiki>--reply=no</nowiki></code> flag, if you get output saying
+
<code><nowiki>the --reply option is deprecated; use -i or -f instead </nowiki></code> remove the <code><nowiki>--reply=no</nowiki></code> flag and type no in the terminal for each plug-in.
+
*If you want to keep the original Ubuntu icon for Firefox, enter this command:
+
<pre><nowiki>
+
sudo cp /usr/share/pixmaps/firefox.xpm /opt/firefox/chrome/icons/default/default.xpm
+
</nowiki></pre>
+
Some users may find the icon with a different extension, they should use this command:
+
<pre><nowiki>
+
sudo cp /usr/share/pixmaps/firefox.png /opt/firefox/chrome/icons/default/default.xpm
+
</nowiki></pre>
+
* To ensure that other programs use version 2 of Firefox and not the old 1.x version, go to Preferences -> Preferred Applications in the System menu. For the "Web Browser" tab, choose "Custom" and then enter the command:
+
<pre><nowiki>
+
firefox %s
+
</nowiki></pre>
+
* Firefox 2 should now be installed and working properly.  If for whatever reason you become unhappy with Firefox 2 and would like to remove it, see the "Removing" section below for directions.
+
=== Restoring Extensions and Themes ===
+
In addition to restoring your settings, you can also restore your themes and extensions.  As indicated above, this should only be done after running Firefox at least once and fully closing it.
+
* Backup the new profile (just in case):
+
<pre><nowiki>
+
cd ~/.mozilla/firefox
+
mkdir ffbackup
+
mv profiles.ini *.default ffbackup/
+
</nowiki></pre>
+
* Restore your previous profile:
+
<pre><nowiki>
+
# Shutdown firefox
+
cp ~/.mozilla/firefox1.x.ubuntu/profiles.ini .
+
cp -r ~/.mozilla/firefox1.x.ubuntu/*.default .
+
</nowiki></pre>
+
* Start Firefox and try it out.
+
A dialog may appear indicating that one or more extensions and/or themes are not compatible. This is normal and Firefox may be able to find the updates for you.
+
=== Updating from 2 to a later version ===
+
Backup your profile with:
+
<pre><nowiki>
+
cp -R ~/.mozilla ~/.mozilla.backup.20x
+
</nowiki></pre>
+
(You may also want to consider backing up the profiles of other users on the system as they will be affected by the upgrade too).
+
There are two ways you can update Firefox to the newest version:
+
The first way is to close Firefox and give your user (yourself) file ownership: <pre><nowiki>sudo chown -R ${USER}:${USER} /opt/firefox
+
</nowiki></pre>  Start Firefox normally and update (Help -> Check for updates...)  Once the update is completed, close Firefox and then '''restore ownership to root''': <pre><nowiki>sudo chown -R root:root /opt/firefox
+
</nowiki></pre>  Do '''NOT''' browse other sites while firefox has these elevated permissions, that is without changing back the ownership of /opt/firefox over to root. Such a practice is ''not safe''.
+
To update firefox you can run Firefox from the terminal with <pre><nowiki>gksudo firefox
+
</nowiki></pre> Be sure to close any running version of Firefox first. Enter your password where prompted. Then check update ('''Help''' -> '''Check for updates...'''). If updates are found, apply the update and when it asks to restart, use the '''Restart''' option. When Firefox starts, you should see a Mozilla page confirming that you're using the latest version. Close Firefox and open it as a normal user (the way you usually open it). Firefox should now be updated to the newest version for all users. This way you don't have to change any file permissions and you won't forget to not change them back.
+
Note that in the second method, you must use the command <pre><nowiki> gksudo firefox
+
</nowiki></pre> Do not use <pre><nowiki> sudo firefox
+
</nowiki></pre> instead as it may give some files in your home directory root ownership and cause problems.
+
=== Removing ===
+
If for some reason you want to undo the installation and revert back to the standard Firefox 1.0.7, here's how:
+
* Restore the symbolic links:
+
<pre><nowiki>
+
# First, /usr/bin/firefox
+
sudo rm /usr/bin/firefox
+
sudo dpkg-divert --rename --remove /usr/bin/firefox
+
# Then, /usr/bin/mozilla-firefox, used as the default gnome browser
+
sudo rm /usr/bin/mozilla-firefox
+
sudo dpkg-divert --rename --remove /usr/bin/mozilla-firefox
+
</nowiki></pre>
+
* Restore your old profile:
+
<pre><nowiki>
+
cd
+
mv .mozilla .mozilla-20
+
mv .mozilla.ubuntu .mozilla
+
</nowiki></pre>
+
* (optional) Delete the firefox directory:
+
<pre><nowiki>
+
sudo rm -r /opt/firefox
+
</nowiki></pre>
+
=== Installing Firefox as a Debian package ===
+
Since it is nice to have a package (easier to upgrade, etc), there is an experimental package building tool at [http://kidsquid.com/programs/ubuntu/firefox-1.5.0-0nonfree1_i386.tar.gz]
+
It can automatically download the i386 version of Firefox 1.5 (or you can copy in your existing Firefox download), then it will create a .deb package for it. 
+
Follow the steps in the README to install the new package.
+
Please do not distribute any files created by this tool, as copying these files may violate the Firefox license.
+
=== Installing Firefox (Quick and Dirty) ===
+
Some people are too lazy or too impatient to install Firefox the way it '''should''' be in Ubuntu (see section '''1'''). This section is '''not''' the proper installation method. It is also '''not safe''' compared to "Section 1". This current section is only for those too lazy and / or too impatient and / or need a quick fix to temporarily use a nightly Firefox trunk. Please note that if you follow this installation option instead of the others, you ''may'' have '''problems''' with some plugins. The instructions to install are basically: unzip, move existing profile, change file permissions, run. The instructions to update are basically: change file permissions, launch and update, change file permissions back. The instructions to uninstall are basically: change file permissions, delete its folder. During these instructions, do '''not''' use <code><nowiki>sudo</nowiki></code> except when apt-getting the prerequisite (dependency).
+
If you are following these instructions to try out Firefox 2.x alpha/beta, please make sure to backup your profile and use a new one if possible.
+
==== Installing Firefox (Quick and Dirty) ====
+
1. Install the prerequisite: '''You need package 'libstdc++5' installed'''.
+
  
<pre><nowiki>
+
== Installing versions of Firefox in testing ==
sudo apt-get install libstdc++5
+
=== Security-testing packages ===
</nowiki></pre>
+
'''Medium difficulty, medium safety''': security-testing packages are halfway through the quality-assurance process.  Although bugs are rare, no guarantees are given.
2. Download the tar.gz archive from the [http://www.mozilla.org/ Mozilla] site to /home/username (username is your own username; adjust to your settings).
+
Users of the most recent Ubuntu release can get new versions of Firefox a few days early from the semi-official ''ubuntu-mozilla-security'' archive.  This archive holds updates to the Mozilla suite (including Firefox) while they're tested for security and stability.
3. Untar to home:
+
To get packages that have not yet been tested for security:
 +
<ol><li>Go to the [https://edge.launchpad.net/~ubuntu-mozilla-security/+archive/ppa ubuntu-mozilla-security personal package archive].
 +
</li><li>Karmic 9.10 or later: Add '''ppa:ubuntu-mozilla-security/ppa''' to your system's Software Sources.
 +
</li><li>Jaunty 9.04 or earlier: Follow the [https://edge.launchpad.net/+help/soyuz/ppa-sources-list.html official instructions] on how to use software from a PPA.
 +
</li><li>Install the package for the new version of Firefox (e.g. this was ''firefox-3.5'' when Firefox 3.5 was being released)
 +
</li><li>A package without security testing will be made available a few days before general release
 +
</li><li>[[UbuntuWiki:MozillaTeam/Bugs|Report|any bugs]] that you experience - especially anything that previously worked, then stops working</li></ol>
  
<pre><nowiki>
+
=== Daily updates ===
cd
+
'''Medium difficulty, low safety''': daily packages have not undergone any quality assurance.  Daily packages are sometimes very safe, and sometimes don't work at all.
tar -xvzf firefox-2.0.0.1.tar.gz
+
Users of recent Ubuntu releases can get the latest development version of Firefox from the semi-official ''ubuntu-mozilla-daily'' archive.  This archive holds updates to the Mozilla suite (including Firefox) that are ''under active development'' - for example, ''preview versions of Firefox 3.6.2pre and 3.7a1,'' were available at the time of writing.  Although these packages will work well most of the time, you should expect crashes and other problems.  To get packages that are only half-finished:
</nowiki></pre>
+
<ol><li>Go to the [https://edge.launchpad.net/~ubuntu-mozilla-daily/+archive/ppa ubuntu-mozilla-daily personal package archive].
4. Change permissions so that something does not overwrite your Firefox files:
+
</li><li>Karmic 9.10 or later: Add '''ppa:ubuntu-mozilla-daily/ppa''' to your system's Software Sources.
 +
</li><li>Jaunty 9.04 or earlier: Follow the [https://edge.launchpad.net/+help/soyuz/ppa-sources-list.html official instructions] on how to use software from a PPA.
 +
</li><li>Install the package for the new version of Firefox (e.g. this was ''firefox-3.6'' when Firefox 3.6 was being released)
 +
</li><li>A snapshot of a recent development version will be available immediately
 +
</li><li>[[UbuntuWiki:MozillaTeam/Bugs|Report|any bugs]] that you experience
 +
</li><li>To stop the ubuntu-mozilla-daily PPA riding roughshod over the Official Repositories consider [http://ubuntuforums.org/showpost.php?p=8636047&postcount=36 Pinning].</li></ol>
  
<pre><nowiki>
+
As these packages install in their own directories and each use separate profiles, you can use 3.6/3.7 side by side.
chmod -R uog-w /home/username/firefox
+
The new Firefox 3.6 will be found under the name "Namoroka Web Browser" and 3.7 under "Minefield 3.7 Web Browser" in Applications > Internet.
</nowiki></pre>
+
This allows them to be distinguishable on the desktop and removes the need to alter any existing links.
5. Move existing Mozilla Firefox profile:
+
== Installing from the Mozilla website ==
 
+
'''Medium difficulty, medium safety''': Sharing the same Firefox profile between different versions of Firefox (e.g., 3.0 and 3.5) may cause problems. As long as you avoid sharing a profile between versions (something which applies to all of the above methods, as well), Mozilla builds are safe to use, since they have undergone extensive QA prior to release.
<pre><nowiki>
+
Please wait until the Ubuntu Mozilla Team make a stable version of Firefox available for your release. If you can't wait and want to use a Mozilla build of Firefox, see the [[UbuntuHelp:FirefoxNewVersion/MozillaBuilds|guide for installing Mozilla builds]].
cd
+
== See Also ==
mv .mozilla/firefox ./firefox.oldfx
+
* This page was based largely on a [http://www.asoftsite.org/s9y/archives/160-FAQ-Where-can-I-get-firefox-3.5-for-Ubuntu.html blog post] by the head Ubuntu Firefox developer
</nowiki></pre>
+
* [http://www.asoftsite.org/s9y/archives/161-FAQ-Why-is-my-firefox-3.5-still-called-Shiretoko.html Another blog post] explains why new versions use codenames and different icons
6. Run Firefox.
+
 
+
<pre><nowiki>
+
cd /home/username/firefox/
+
./firefox
+
</nowiki></pre>
+
That's all.
+
You can manipulate existing shortcuts to point to the newly installed Firefox, or create new shortcuts.  
+
==== Recovering Bookmarks (After a Quick and Dirty Install) ====
+
Your old bookmarks can be imported into your new install:  
+
In your new Firefox install, go to Bookmarks > Manage Bookmarks > File > Import and navigate to
+
<code><nowiki>/home/username/firefox.oldfx/somenumbers.default/</nowiki></code> and choose bookmarks.html.
+
==== Updating Firefox (If Installed Using Quick and Dirty guide) ====
+
1. Change permissions of Firefox so it can write to itself:
+
 
+
<pre><nowiki>
+
chown -R u+w /home/username/firefox
+
</nowiki></pre>
+
2. Launch Firefox:
+
 
+
<pre><nowiki>
+
/home/username/firefox/firefox
+
</nowiki></pre>
+
3. Go to Help > Check for updates and update as needed. As with any update, you may want to backup your profile beforehand.
+
4. Close Firefox.
+
5. Restore permissions:
+
 
+
<pre><nowiki>
+
chmod -R uog-w /home/username/firefox
+
</nowiki></pre>
+
That's all.
+
==== Uninstalling Firefox (After a Quick and Dirty Install) ====
+
This is not too difficult:
+
1. Change permissions (as usual):
+
 
+
<pre><nowiki>
+
chmod -R u+w /home/username/firefox
+
</nowiki></pre>
+
2. Use Nautilus (or any other file manager) to navigate to /home/username/ and delete the folder "firefox" (just for repeatition : you will be deleting /home/username/firefox -> the folder you untarred Firefox into).
+
3. Move your old profile (from 1.0.x) back to it's place:
+
 
+
<pre><nowiki>
+
cd
+
mv .mozilla/firefox .mozilla/firefox.150.uninstalled
+
mv firefox.oldfx .mozilla/firefox
+
</nowiki></pre>
+
That's all.

Introduction

When a new version of Firefox comes out, there is some delay until it can be downloaded and run. This page will explain how to install Firefox as soon as possible. The Check For Updates link in Firefox is disabled in Ubuntu. Firefox should only be updated through the package-management system.
