  • Justyn says:

    I added the repository into ubuntu, but it still seems to update to the RC2 release, not the final.

    I think I will wait for ubuntu to update their repository.

  • kylehase says:

    sudo sh -c “echo deb http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu jaunty main > /etc/apt/sources.list.d/mozilla-daily.list”

    sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 247510BE

  • Simone says:

    Hi, thanks for your tips. I followed all the steps in order and I installed firefox 3.5 but when I type in the terminal ~/firefox/firefox the system starts Firefox 3.0

    Where am I wrong?

  • Kwame says:

    echo ‘deb http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu jaunty main’| sudo tee -a /etc/apt/sources.list

    is also a good option.

  • Tazjin says:

    Can’t get the package key >.>
    keyserver.ubuntu.com keeps timing out.

  • luckybear says:

    Thank you thank you thank you! Just switched to Ubuntu and i had no idea how to update firefox to 3.5 Not used to running terminal commands. Worked perfectly. Your instructions were easy to understand. :)

  • Aldi says:

    @ kylehase: I have the same problem. Firefox 3.0.11 starts. However,from the console it is possible to start firefox-3.5.

    Then I deinstalled Firefox 3.0.11 and the new version did not work either after that. … Any solution?

  • hacktolive says:

    Hi, feel free to delete my link, but I have made a portable version of Firefox for Linux (Ubuntu):


    This avoids the need to install


  • x33a says:

    @ Kylehase,

    start it using firefox-3.5.

  • x33a says:

    oops, sorry i meant Simone.

    start firefox with firefox-3.5 (from the terminal).

  • Hoai Huong says:

    I can’t update or install Firefox3.5 because the public key was not available. How do you correct it?

  • Multitude says:

    Get the key here:


    and install it with these instructions:


    This worked for me.

  • Simone says:

    Sure I can start if from terminal, but there is a way to change the linux shortcut in order to link directly to 3.5? Avoiding me to start the program from the terminal each time?

  • Kwame says:


    Well, /usr/bin/firefox is a symbolic link pointing to /usr/bin/firefox-3.0. So you can do:

    sudo rm /usr/bin/firefox
    sudo ln -s /usr/bin/firefox-3.5 /usr/bin/firefox

    I’ve tried it on Jaunty and my system has been stable for the last 16 hours or so it works but this is a very quick and dirty hack. if you’re not comfortable mucking around your sytem, I’d advise against it

  • Jigs says:

    I can’t seem to download the key either with the command given. What’s the solution?

  • SilverWave says:

    It you set your sources in Ubuntu to allow Proposed Updates then FF3.5 is available :)

    Was: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1b4pre) Gecko/20090401 Ubuntu/9.04 (jaunty) Shiretoko/3.5b4pre – Build ID:20090401172919

    Now: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1) Gecko/20090701 Ubuntu/9.04 (jaunty) Shiretoko/3.5 – Build ID: 20090701021524

    Remember to then turn proposed off :)

  • Aldi says:

    @Silverware: Thank you for this! A general question regarding the repository Jaunty-proposed:
    If I install FF 3.5 from Jaunty Proposed and then switch the repository Jaunty Proposed off, will the package manager update automatically to 3.5.1 as soon as this will get into Jaunty Universe? Or is the package manager generally not smart enough and marks a package only for update, if it is from the same repository?

    Or in other words: Does it make sense to wait until FF3.5 will be Jaunty Universe?


  • JackV says:

    I currently used the method 2. But is download from the firefox website(using firefox 3). But after exact it out. I run ./firefox after i cd into the directory. It output
    “./run-mozilla.sh: 399: ./firefox-bin: not found”

  • Pablo says:

    Sure you can try the method suggested by Kwame, but I would recommend that you first try this one:
    change the Properties of the Firefox icon on the panel ->Command section to “firefox-3.5 %u” (without the quotation marks). Thus you will just change the command, without changing the links, so that you be able to go back to previous settings easily ;)

  • Eichhorn says:

    Hi, thanks, but i have a problem, i installed firefox 3.5 through terminal and installed, but it’s still shaws 3.0.11 version in firefox’s help!

  • Pablo says:

    In case you start Firefox using the old icon on the panel, you should change the properties of the icon(right-click -> Properties->Command) to “firefox-3.5 %u”(without quotation marks). Thus the icon will point to the right executable.

  • MoGlee says:

    Thanks for this post, I finally got FF 3.5 running on Ubuntu!

    BTW, Firefox 3.5 is the FASTEST browser??? Since when?

    http://lifehacker.com/5286869/lifehacker-speed-tests-safari-4-chrome-2-and-more and http://www.favbrowser.com/safari-4-vs-chrome-2-vs-opera-10-vs-firefox-35-vs-opera-964-vs-firefox-3-vs-ie8-7/ – Chrome and Safari 4 are clearly much faster

    Well I suppose since there is no Chrome/Safari for Linux as yet, you could say that, but still!

  • Bones says:

    When I run firefox-3.5 from the terminal, it opens “Shiretoko.” What is that?

  • Jay says:

    Can I use this on use these methods on Xubuntu 9.04

  • ejwaxx says:

    “Shiretoko” is the code name for the testing version of Firefox 3.5. Current release of Firefox is 3.5.2, Shiretoko is the pre-release version of 3.5.3.

  • Talal Arshad says:

    A better and easy way..Shiretoko has problems try this method this will install the original firefox 3.5

  • A Commenter says:

    I’m on ubuntu 9.04. I had the same issue upgrading to 3.5.2 – running firefox still showed version 3.0.13.

    If you use the ‘ln’ command (in previous post) then you may have to update more symbolic links for completeness:

    # Display all files that match the pattern ‘fire’ (ignoring case sensitivity)
    sudo ls -l /usr/bin | grep -i fire

    You’ll find there’s another link for ‘abrowser’ pointing to firefox-3.0:

    After these commands I was up and running on firefox 3.5.2:
    sudo rm /usr/bin/firefox
    sudo ln -s /usr/bin/firefox-3.5 /usr/bin/firefox
    sudo rm /usr/bin/abrowser
    sudo ln -s /usr/bin/firefox-3.5 /usr/bin/abrowser

  • anthony says:

    Hi, I use Ubuntu 9.04 and I have tried to update Firefox from 3.0 to 3.5 for hours.
    Then I have found page:

    I think, it is “GOOD WAY” :-)) I can recommend it, Firefox 3.5.3 runing perfectly in a few moments :-))
    If you are in troubles, try it !!

  • yudie says:

    YUPIEE THIS IS THE SOLUTION MY PROBLEM AFTER INSTALL MOZZILA 3.5 In case you start Firefox using the old icon on the panel, you should change the properties of the icon(right-click -> Properties->Command) to “firefox-3.5 %u”(without quotation marks). Thus the icon will point to the right executable.
