Yes, you should keep all data in the Firefox profile folder when Firefox updates.
Firefox will do a compatibility check for extensions.

It is never a bad idea to backup your personal data in the profile folder, so if you never done that then this is a good time to start doing this.

Great -- I'll read over those articles and back up my profiles. Thanks for the answer and the links -- much appreciated! :)

Hi again, cor-el,

I just came across another thread in which I posted the following question; however, it'd be great to get your input here, since it seems relevant to this thread as well. Sorry for the cross-post:

I am using Windows XP (sp3) on an older laptop. Am I going to run into any problems that you know of when updating to FF 22.0?

Thanks!

As jscher2000 posted in the other thread, there is always a possibility that security software is causing problems.
Most of the time it should work fine.
So in the case that there are problems then check that first and if necessary boot the computer in Safe Mode (press F8 on the boot screen) to disable such software temporarily.

If there are problems with hardware acceleration in Firefox then hold down the Shift key when starting Firefox to start in Safe Mode.
