Firefox 3 Beta 2 is a developer preview release of Mozilla's next generation Firefox browser and is being made available for testing purposes only.

These beta releases are targeted to Web developers and our testing community to gain feedback before advancing to the next stage in the release process. The final version of Firefox 3 will be released when we qualify the product as fully ready for our users.

Firefox 3 Features

Firefox 3 is based on the new Gecko 1.9 Web rendering platform, which has been under development for the past 28 months and includes nearly 2 million lines of code changes, fixing more than 11,000 issues. Gecko 1.9 includes some major re-architecting for performance, stability, correctness, and code simplification and sustainability. Firefox 3 has been built on top of this new platform resulting in a more secure, easier to use, more personal product with a lot under the hood to offer website and Firefox add-on developers.

Installing Firefox3.0 beta2 in ubuntu

Preparing your system

sudo apt-get install libstdc++5

Now you need to take backup of your old firefox prferences

sudo cp -R ~/.mozilla ~/.mozillabackup

Now you need to download firefox 3.0b2 from here

Now you have firefox-3.0b2.tar.bz2 file

Unzip the .tar.bz2 file in /opt directory using the following command

sudo tar -C /opt -jxvf firefox-3.0b2.tar.bz2

Now you need to link the plugins using the following command

cd /opt/firefox/plugins/

sudo ln -s /usr/lib/mozilla-firefox/plugins/* .

Now you need to create a link to your new firefox launcher using the following command

sudo dpkg-divert --divert /usr/bin/firefox.ubuntu --rename /usr/bin/firefox

sudo ln -s /opt/firefox/firefox /usr/bin/firefox

sudo dpkg-divert --divert /usr/bin/mozilla-firefox.ubuntu --rename /usr/bin/mozilla-firefox

sudo ln -s /opt/firefox/firefox /usr/bin/mozilla-firefox

This will complete the installation of firefox 3.0b2

    I did some shit. As it is told, the new installation replaced the old one. That would be no problema, if the flash player worked in firefox 3.0.

    Could you please post a how to get back the old version or the solution to flash player?

    In my Gutsy for Fiorefox Flash to work this line

    sudo ln -s /usr/lib/mozilla-firefox/plugins/* .

    has to be changed to

    sudo ln -s /usr/lib/firefox/plugins/* .

    Default directory has different name. And btw how to remove Firefox beta 2 completely ? Its very heavy on my CPU when I open more than 3 or 4 tabs.

    What do you see when you go to about:plugins ? Do you see all of the plugins that you see for firefox 2? I can’t figure out how to get my old plugins to register.

    Thanks!

  8. k-caj says:

    I’ve tried installing like this on my ubuntu 7.04 and it’s not working (it says “file doesn’t exist” when I try to start firefox, but there is firefox folder in /opt and I’ve checked all commands twice, I did everything like you said)

    Are there any additional steps for 7.04? What can i check to see what I did wrong?
    Or, can you tell me how to undo all that, so I can have my FF2 back?

    (please, as simple as you can – I’m a designer, and I’m using ubuntu just for testing my websites, my knowledge for installing new things stops at apt-get… :)

  9. Jack Kerouac says:

    NONE of my plugins work now, especially JAVA. Can you PLEASE post a method of removing Firefox 3 Beta 2?

    [Reply]

  10. Jack says:

    I managed to roll back to Firefox 2 by doing:

    Code:

    $ sudo rm /usr/bin/firefox
    $ sudo rm /opt/firefox
    $ sudo dpkg-divert –rename –remove /usr/bin/firefox
    $ sudo apt-get install firefox –reinstall

    I will wait for the official Firefox 3 release. I looking forward to it but I can not stand a minute without AdBlock.

    tar: firefox-3.0b2.tar.bz2: Cannot open: No such file or directory
    tar: Error is not recoverable: exiting now
    tar: Child returned status 2
    tar: Error exit delayed from previous errors

    What is the problem?????

  13. Goran says:

    This is really annoying: I cant get the flash plug-in to work, nor can I reinstall FF2.
    This how-to sucks…

  14. Kansu says:

    Chris and Darkshade,
    Either cd into the directory that contains your downloaded firefox-3.0b2.tar.bz2 file or specify the path to this file in your command. That is:

    either do the following if firefox-3.0b2.tar.bz2 was saved to, for instance, your Desktop:

    cd ~/Desktop

    and then do sudo tar -C /opt -jxvf firefox-3.0b2.tar.bz2

    OR

    do

    sudo tar -C /opt -jxvf ~/Desktop/firefox-3.0b2.tar.bz2

    Hi I have a dual boot win/ubuntu laptop. I’ve just installed Firefox 3 Beta 2 on Windows in a single simple step (double click the exe). Why is this task so bizantine in Ubuntu?

  16. Adross says:

    You can unzip the tar.gz file and install firefox 3 in a similiar fashion to it’s windows counter part. This is just provides a more elegant install.

  17. krishna says:

    You can now install the latest Beta RC by enabling backports and then apt-get’ing firefox-3.0. This is the best way to do the install as it won’t replace or override your firefox 2 install – it will even make new ~/.mozilla/firefox-3.0 profile settings (although it will import your settings from firefox 2, it won’t replace them).

    to install your plugins (eg, flash), just sudo cp /usr/lib/firefox/plugins/* /usr/lib/firefox-3.0/plugins (or ln -s, either will work)

    i’d definitely recommend doing the install this way, as you won’t have any problems with this beta 3 replacing your stable 2 (although as far as i can tell, 3 is definitely stable enough now for normal use)
