  1. great, simple and painless! Thanks!

    I was already coming from 4.0b13pre(2011-03-22) and that helps.

    But: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.15pre) Gecko/20110207 Lightning/1.0b2 Shredder/3.1.9pre was/is a part of the daily build PPA. Now what happens with TBird and Lightning? Just wait for “final” versions?

    Thanks!

  2. I thought Canonical stated last year that Ubuntu would now be updated to the latest Firefox milestone via the repos as well as point release security updates. I know I remember reading that announcement. Does anyone else recall this?

  3. Thank you very much. I’m new in ubuntu, but I really like it very much. It’s a bit difficult sometimes, as I came from the Microsoft OS, but it’s just the begining.
    Thank you very much one more time.

  6. Nope, still 3.6. Does not upgrade to 4. This merely updates your installed version of 4, so the title is a lie.

  7. Thanks for the information! No Luck here though. :-(

    Followed the instucts. Last command sudo apt-get upgrade “Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.”

    This is a dual boot machinator. Firefox 4 already on Windosw7.

  9. We’re on ff 8 now, any ideas how to go back to v7 (or older)? The usual method of version selection doesn’t seem to work, I’ve tried “apt-get install firefox=7.0″
    Cheers :)
