How do I remove an old version of Flash from addons after updating?
I recently updated from Firefox 5.0 after a long period of not-updating to Firefox 22.0, and immediately had to update Flash (which I also hadn't updated in awhile as in FF5.0 updating past 11.2.202.235 borked Youtube). However, now I have two different listings in the Add-ons Manager for Flash, one for 11.8.800.94 and another, flagged as 'Shockwave Flash is known to be vulnerable and should be updated', for 11.2.202.235. I tried manually disabling it, but the next time I opened Firefox they were both disabled. Also, I'm having issues with Youtube videos stuttering and chugging (although, oddly, with no apparent drops in framerate) in Firefox after updating, that don't happen in Chrome, and I'm wondering if somehow thiis might be the cause?
So I was wondering, is there a way to remove the 'old' Flash from Firefox? I already checked add/remove programs and there is only one Flash 11 there, at the date it was updated.

Yes this is caused by a flash install problem, try removing it from the control panel (Both) and try again.
Thanks. I followed the procedure there, and now there's only the one Flash. :) However, I'm still noticing a /slight/ choppiness in Youtube videos that doesn't seem to be in them when viewed on Chrome. I tried completely uninstalling and reinstalling Flash, but no improvement, and unchecking hardware accelleration doesn't either.
And also, I just noticed that when I hold down the spacebar in this box (or the address bar), the progress of the cursor isn't smooth - there's just enough pause in its progress between each character to make it noticably 'jerky'.
Was this in flash or in firefox (disabling hardware acceleration)?
For flash refer to => http://forums.adobe.com/thread/891337

You should also check for upgrades to your graphics drivers or try Firefox safe mode.

Yes, I didabled accelleration in both places, and it had no effect on the video. I should note that this is only "sometimes" - right now, for instance, the cursor is moving smoothly when I hold down the spacebar, and videos aren't /always/ choppy.
Also look at some more of that page i posted in my first post
I should add that I tried opting-in to the Youtube HTML5 test, with no result. I'll poke around at the other stuff in the morning possibly.
Type about:plugins in the URL bar and hit Enter.
Look for that older Shockwave Flash 11.2 r202 plugin and note the Path: C:\....
Navigate to that file via the Windows Explorer file system and delete that file. Then restart Firefox.
