Flash Player Crashing After Updating to FF 15

Just updated to FF 15 and the Flash Player crashes any time I load a page with a Flash object. I'm running Flash 11.4 r402 on Windows 7 32bit. I tried safe mode and that did nothing to solve the problem. All help appreciated.

Ok it seems the best temporary solution to this problem (until they release a new version of flash) is to uninstall Adobe Flash Player and then download an old version of Adobe Flash Player (11.2 worked for me - don't use 11.3 because it has problems too).

The Shockwave and Java applications may need 'PLUGIN UPDATE' for newer versions. Suggest a check for any outdated PLUGIN UPDATE found from the Mozilla Firefox Toolbar 'Help' Menu > 'Firefox Help' > [lower right margin displays link to more info to review and 'UPDATE PLUGIN's!

Re: Flash Player Crashing After Updating to FF 15

Obviously the first thing I tried was updating Flash (and all my other plugins). I am using the latest version of Flash (11.4.402.265) and I am also using the latest version of Firefox (15.0).

Also, there appears to be two ongoing questions about this same problem, both of which appear to be about a day older than this question, and both of which remain unsolved.

May I suggest to the admin/mods to close this question and everyone can continue to give input on this problem at one of these two questions (I will keep my eye on them too).

OMG.... some one fix this crap already. How long are we going to have to deal with this extremely critical problem, and I'm not about to turn off flash's protected mode as a last resort. I've been reduced to using Chrome now. The horror.

Re: Flash Player Crashing After Updating to FF 15

I can not successfully install Adobe Flash Player 11.4 on FF 15.

With each new release of FF, I have to go through this procedure.

When I try to go back to Adobe Flash Player 11.2 I still get still get crashes on installation. I get caught in a near infinite loop of the kind of error message displayed in the attached screen shots.

Task Bar -> Close does not work. Alt+F4 does not work. I must be missing something, because the only way I can to stop the install is by killing the process, or killing the entire process tree in Task manager. Not good.

How do I leave the Beta team and get back to work?

I am becoming quite desperate, but not enough to give up on FireFox.

Try to "disable the hardware acceleration" in the Flash Player.

Try to clear the Flash local storage and settings.

@FoxPhoenix: well that sounds like an entirely different problem so I would recommend that you start another question if you want you problem solved.

@cor-el: the problem with that solution is that the settings manager requires Flash to work. This bug entirely disables all use of Flash Player.

Re: Flash Player Crashing After Updating to FF 15

I agree! I'm not computer savvy enough to go in and start disabling protected mode, and from what I understand that's not a good idea to begin with. The situation actually improved somewhat for a few weeks prior to the latest updates of Flash Player and FF (which happened within a few days of each other)....there weren't nearly as many crashes. Now with the most recent updates, it's happening continually all over again! Since Flash Player works fine in IE, I'm inclined to think the problem is on FF's end. Surely there must be a solution without having to jump through hoops. Everything was fine until this Summer!

After spending an hour on this with one of the IT guys at work, we solved the problem by uninstalling Real Player.
