Install firefox 3 beta 3 on ubuntu

So I decided to give firefox 3 b3 a try. And it’s great!

I ditched firefox 2 because it’s was to slow and crashed alot.

I’ve been testing ff3b3 for a few hours now and I haven’t got the famous flash crash yet.

Oh, did I mention it’s lighting fast?

Let’s install this bad boy (this will replace firefox 2)

Download the file here (save it on the desktop)

Just copy past this into the terminal.

sudo tar -C /opt -jxvf /home/username/Desktop/firefox-3.0b3.tar.bz2

cd /opt/firefox/plugins/

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


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

the line before divert and rename is “- -” without the space, wordpress formats them to 1

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

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

the line before divert and rename is “- -” without the space, wordpress formats them to 1

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

You can read all about the new features here.

I had to add firefox to the “applications -> internet” again.

Move your mouse above “applications” and right click it. Choose to “edit menu”, select”internet” on the left, then select “new item”on the right. Fill this in:

– Firefox 3 beta 3
– firefox
– web browser

Then hit ok. The icon picture should be added by default.

If you had java and flash support in firefox 2, you’ll have it in ff3.

Have fun.

ps: I only tested this on ubuntu 7.10 with all the latest updates installed as of feb 15 2008.

  1. Or, you could just apt-get install firefox-3.0

    It’s in the Universe repository.

    The newer versions can take a bit longer to get into the repo’s so you can use this to install the next versions also.

  2. Hello,

    I tried your blog instructions and it seems to fail at this point

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

    Any ideas?

    Thanks, NullHead

    Since firefox beta 3 is now in the repo’s you can install it now using:

    sudo apt-get install firefox-3.0

    The version that is in the repos is NOT firefox 3.0b3. It is just firefox 3.0b1 and therefore this install method works the best to get the latest version.

    Thanks again mate, works real well

    Yeah, sorry for that.

    Firefox beta 3 still isn’t in the repo’s.

    (the version in synaptic is still alpha 8 )

    The two “sudo dpkg-divert” do not work if copied from the webpage to the command line as the –divert and –rename arguments appear to get changed to a single “–”.

    I think this probably some automatic formatting done by the blogging software.

    If you type the commands out manually or correct the “–”‘s the command works perfectly.

    Same thing happened to my comment 🙂

    The “-“‘s should be “- -” minus the space.

    • linuxowns

    That’s correct, I hadn’t noticed it yet but it should indeed be “- -” without the space in between.

    I type these things in “gedit” and just paste everything here.

    However others reported that it works.

    I tried this and it really messed things up… not sure how to fix it now.

    It’s an old article and doesn’t apply anymore.

    Completely remove firefox using synaptic and install firefox using synptic.

    In hardy it’s already firefox 8.04.1

    I can’t remove firefox after following these instructions and I can update it. I keep getting errors that I’m trying to overwrite a diverted version. Can anyone please tell me how to undo this??
