Downgrade Firefox from 21 to 20 - what about addons?
Hello, I'm planning to downgrade from FF21 to 20, because I work with Firebug addon and it seems there's something in FF21 that slows down it to an unusable speed. To keep working, I MUST downgrade.
Here's my question: will I lose all my addons if I downgrade Firefox? Thanks

hello, you won't lose any extensions unless one of them is explicitly specifying it will only work with firefox 21 & above - which is rather unlikely (in this case it would show up as disabled in the addons manager).
You can also give the Firefox 22 beta version a try to see if that works better.
It is usually not a good idea to downgrade.
Be sure to do a custom install and install this version in a separate program folder and create a new profile. I.e. do not launch the beta version after the installation has finished, but use the Profile Manager to create a new profile and use a desktop shortcut to start this version with this profile (-P "Profile Beta").
This has been reported to the Firebug developers: Issue 6458 - fbug - Firebug 1.11.3 makes webs incredibly slow on Firefox 21. I do not see any sign of a resolution there, although some have reported luck in upgrading to a different version.
In another thread, a user here reported that resetting Firebug settings resolved the issue (see attached screen shot). Another user said that helped, but after a few hours, the problem returned. It sounds as though we don't fully understand the problem yet...

Edit: Upon further review, it appears that the reset might turn off the Console and Script panels, which are the panels that seem to cause the slowness. That definitely is not a long term solution.
