I tried uninstalling it from Ubuntu software center. It gets uninstalled but if I re-install Firefox (not developer edition) then it switches to Firefox developer edition.

How do I ONLY uninstall Firefox developer but keep the bookmarks, URL etc. saved for the retro Mozilla Firefox browser. I don't want to loose any data while shifting from Firefox developer edition to the Mozilla Firefox browser.

  • @blade19899 I checked this thread, before asking and the answer is incomplete Could you clarify that a bit more? What does "via > downloads > next > programs > etc" refer to? Directories? – swapnesh Dec 22 '14 at 10:24
  • How did you install it in the first place? – blade19899 Dec 22 '14 at 10:26
  • @blade19899 sudo apt-add-repository ppa:mozillateam/firefox-next sudo apt-get update && sudo apt-get upgrade and I don't know its ask about the firefox dev edition update and unfortunately I clicked that – swapnesh Dec 22 '14 at 10:27

To remove the Firefox Developer Edition from ppa, use ppa-purge.

First close the Firefox Developer Edition, then run the following:

sudo apt-get install ppa-purge

And then remove the ppa:

sudo ppa-purge ppa:mozillateam/firefox-next

I am not sure if it will keep your Firefox data! But by using Firefox Sync, you can backup everything just in case it deletes everything.

After that remove packages that FDE required, but are no longer needs.

sudo apt-get autoremove

Then reinstall firefox:

sudo apt-get install firefox

  • OMG..its giving me the worst experience with Firefox this time..I run the above mentioned commands..and uninstall FF from ubuntu software center..now If I re install from ubuntu s/w center..its switching to the same developer edition..worst experience with firefox this time:( – swapnesh Dec 22 '14 at 11:25
  • @swapnesh ? If you runned: ppa-purge ppa:mozillateam/firefox-next, Firefox Developer Edition is already removed. Try on top of that: sudo apt-get install firefox. And then reinstall it sudo apt-get install firefox. – blade19899 Dec 22 '14 at 11:28

Had to uninstall this PPA. The rest of the instructions worked as expected, and my original Firefox profile was restored.

sudo ppa-purge  ppa:ubuntu-mozilla-daily/firefox-aurora

For those who installed firefox developer edition using ubuntu-make, you can delete the symlink ~/.local/share/umake/bin/firefox-developer and the folder ~/.local/share/umake/web/firefox-dev.

If you want to unkinstall umake completely, run

sudo apt-get purge ubuntu-make

And then delete the folder ~/.local/share/umake, as the purge will not remove it.

On Fedora I was able to simply rename the 'firefox' directory, reinstall firefox and reimport my bookmarks. It is cleaner to remove the old directory if you prefer, but as they say if it works don't fix it.

Make sure all your Firefox specific data to your Firefox Account (if you don't have one, it is super easy to set up: go to the three horizontal bars in the tool bar and click where it will say something about sign-in to account to sync).

Then use apt to remove the dev version of Firefox. Be sure to run sudo apt autoremove to remove any leftover configuration files. (Personally, I would also reboot to ensure any old files are removed. But this is not entirely necessary). Then, go and use apt, synaptic, or the software center to re-install Firefox.

Finally, log into your Firefox Account and all your bookmarks, settings, and add-ons will be copied over to the new installation for you.

Hope this helped!
