  1. Hey, JR ~~

    Thanks a bunch for this write up. I actually just used it to install FireFox v5 — yum picked it up automatically. All was easy to follow (i.e. copy & paste!) and worked without a hiccup.

    Good Stuff !!!

  2. Thank you a lot,

    I know this is a old thread but i got firefox firefox-8.0-1 on Fedora 12 :)

    Still have to figure out is it possible to just upgrade fedora to last stable version or I have to make clean new install and delete all stuff I have on it ? :/

    Best Regards,

    • You are welcome!

      Yes, very old thread :)

      Upgrading from Fedora 12 to Fedora 19 is possible, but you need to find old repos, because safest method is upgrade F12 -> F13, F13 -> F14 and so on. So easiest and best way is backup your all important files and do fresh install, then simply restore your old files.
