I foolishly upgraded my Firefox install on Ubuntu to the beta 4 release, I believe by adding the PPA repository -- is there an easy way to roll it back to the 3.6 version provided by Ubuntu?

Can you give some details about how you did the install? Specifically, did you: a) install via a custom apt repository; b) install directly via a .deb package; c) install the binary directly? –  Shane Madden Mar 8 '11 at 1:39
    
He installed it through the PPA, as it says in the original post :) –  Thomas Boxley Mar 8 '11 at 2:45

Yes, try these commands:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:ubuntu-mozilla-daily/ppa 

Which will remove the PPA, sudo apt-get remove firefox-4.0 to remove Firefox 4.0, and sudo apt-get update and sudo apt-get upgrade to refresh the repository sources and upgrade (downgrade) "Namoroka" to plain old Firefox 3.6.

ok, I did this and removed FF4-- however when I refresh and then upgrade, there's no changes made (no install of 3.6 )-- any ideas? –  julio Mar 8 '11 at 22:51

@thomas-- I am not sure how to determine that. I had the daily PPAs in my sources list, until they were disabled on upgrade from 10.01 to 10.10. After that, naturally, I was stuck on FF 4.0 beta 8. I removed the PPAs and purged them, but no rollback happened. –  julio Mar 9 '11 at 17:23

it's Firefox 4.0b8 –  julio Mar 10 '11 at 3:23

If you want a GUI way then you can install Ubuntu Tweak (Download Link) then run it from Applications -> System Tools. Then navigate to "Package Cleaner" and click unlock and select Purge PPAs and select mozilla daily ppa

Then click cleanup and yes to the subsequent dialog

Now launch the software center and search for firefox-4.0 and remove it

Now search for firefox and install it.
