Adobe Flash 12 crashing - Mozilla and all browsers

more options

I suddenly got crashing problems related to Flash this afternoon and I still can't solve it. I've tried everything, manually uninstalling Flash 12; installing a previous version of Flash 11.7; re-installing firefox; flash settings, etc. I tried everything I could and i still can't find an answer for this horrible problem. To make things worst, the flash player doesn't work in any other browser, I've tried on Chrome and all videos do not have any sound, IE has the same problem as Firefox, simply doesn't show anything at all.

Any suggestions? I'm pretty frustrated

That sounds like a nightmare.

I don't know what is causing your issues on other browsers, but each browser uses its own software for Flash, so it's worth trying some Firefox-specific things.

This is some standard guidance that addresses the most common issues with the Flash Player plugin. I'm sure you've seen some of it before, but just in case:

(1) If you have any recorders/downloaders that interact with Flash media make sure they are as up-to-date as possible, or disable them temporarily.

(2) Disable hardware graphics acceleration in Firefox and in Flash

  • In Firefox, un-check the box here and restart:

    orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"

(3) Disable the protected mode feature. The following pages provide different ways to disable the feature:

Any luck?

By the way, in between trying 12.0 and 11.7, did you use the Adobe uninstaller? Mixed files might be an issue. Also, if you haven't shut down and restarted Windows since this problem began, that would be worth a try in case the Windows installer has unfinished business.


When Firefox crashes, or when the Flash plugin crashes, Firefox usually records information about what was happening at that moment. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "Firefox Crashes" (especially the last section) for steps to get those crash IDs, and then post some of the newest ones here if the mitigation steps do not help.
