  1. 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.

  2. 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?

  3. 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. :)

  4. @ 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?

  5. 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?

  6. @Simone

    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

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

  8. 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 :)

  9. @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?


  10. 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”

  11. Simone,
    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 ;)

  12. 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!

  13. Eichhorn,
    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.

  14. “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.

  15. 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

  16. 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.
