Adobe Flash Player 11.4 quits working, won't show videos even after reinstalling.
Had Adobe Flash Player 11.3 r300 and it stopped showing videos, etc. in Firefox a few days ago. Now I've installed v 11.4 r402 and it still gives error message "Adobe Flash Player ... has stopped working." I uninstalled, downloaded again and reinstalled -- with the same result. No videos. Firefox Plugin check page shows it installed correctly. Any solutions?
Chosen solution
by jscher2000For 11.3, one of the workarounds was to disable protected mode. See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox? This appears to still be applicable in Flash 11.4.
You also could consider rolling back to Flash 10.3. However, some content may require new features of Flash 11.x. This article has the steps: Adobe Flash plugin has crashed - Prevent it from happening again.

Warning: Installing Adobe Flash 10.3
The instructions in the 11.3 crash article on installing the 10.3 don't tell you that the Active X Flash version must also be installed because the Adobe Uninstaller uninstalls ALL installed Flash and certain programs require that to work properly. I reported this two months ago and although I was thanked for it it was ignored by Staff and only corrected in the viewing videos problem article, which links to the crash article. If I have to do the job of Staff I'm happy to oblige, since there is no excuse for this. I actually corrected this same error by a Mozilla QA engineer who left out this same step in her testing on a bug report, and I got the expected result, she didn't.
jscher2000's recommendations are good, I'm only supplementing the crash article instructions for anyone who needs that.

Go to answer 18Did anybody ask themselves why would adobe offer Chrome during flash installation ? why they didn't offer Firefox, simply because they are not willing to work with Firefox team to fix the problem which will eventually ends by forcing every body to switch to Chrome specially that YouTube and Google are teamed together so all the features for flash movies played on Firefox will not work while with Chrome it will work. Just my opinion.. The following works for mw: 10.3 plugin - Checkmate link. Firefox 13.01 dom.ipc.plugins.enabled;false dom.ipc.plugins.java.enabled;false dom.ipc.plugins.parentTimeoutSecs;1 dom.ipc.plugins.processLaunchTimeoutSecs;10 dom.ipc.plugins.timeoutSecs;10 dom.ipc.processCount;1
It is been fast, no crashes, on Vista 32bit.

@core-el
- I don't use RealPlayer or anything to do with it.
- Apparently this isn't possible for OS X...
- Despite my symptoms being slightly different to what's described, I've followed the directions here & disabled hw acceleration.
I've also run Firefox in safe-made & was still able to replicate the problem.
So themes/extensions have zero to do with the adobe plugin crash warning I'm getting whenever I go here.
Any other ideas?

jalyst,
There are a number of open Flash plugin bugs, many of which involve crashes (examples).

I've only just come back to this, had a no. of other things to deal with first...
Oddly enough it now seems to be working fine on the site I linked to(1), so hopefully it won't crash on similar flash sites anymore.
Nothing has changed in my entire setup as far as I'm aware, so it's very strange indeed, the site looks like it's had an overhaul though.

jalyst,
Yes, it's possible that the problem was with the website since you say that things are working there now and that Nothing has changed in my entire setup as far as I'm aware, so it's very strange indeed, the site looks like it's had an overhaul though.
If you have any issues with Flash in the future, check these articles first for possible solutions:
