I suggest that you remove all video stuff like flash. Reboot, then go to Mozilla.org or Firefox In Any Language and download the full installer. Then go to the web sites where the flash players are from and download the latest installers. Good luck.

I am having a similar problem on many websites with Shockwave crashes as shown in the attached picture. I have done all that was suggested in this thread: https://support.mozilla.org/en-US/questions/965547#answer-508213 I am almost ready to dump FF.

Yes, that's the same message I get. It isn't just FF on my end, though, it's any web browser.

By "video stuff" do you mean like Quicktime, Java, etc., as well as flash/shockwave?

I have only tried FF, I havent used IE yet, so not sure on that for me. I reinstalled so many things I lost track.

Hi Bob_Loblaw, it's odd that you have the same issue in 3 browsers because each uses a different Adobe component. This suggests that some external process could be involved, whether it's a downloader/recorder, some kind of filter such as security software or parental controls, a firewall, or something about your connection, such as a proxy/private VPN service.

Hi 7246291, is Firefox recording crash information for this Flash problem on your system?

If so, 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 recent ones here.

I dont know if it is or not. How/where would I check?

Hi Bob_Loblaw, your crash reports show a version 1.0 extension. When I search the signature, there are indications that it's questionable. Could you check on what that is and try disabling it temporarily? You can do that on the Add-ons page. Either:

• Ctrl+Shift+a
• orange Firefox button (or Tools menu) > Add-ons

In the left column, click Extensions.

You might also need to remove a user.js file that will re-enable it at the next startup, too. This article has the steps: How to fix preferences that won't save.

Hi 7246291, please try the about:crashes page (type or paste that into the address bar and press Enter) as described in the article I linked to.

here is the url of the latest report:

Hi 7246291, unfortunately that hang signature is linked to several different bugs without a clear path to a solution. If you already ran through the checklist of mitigations*, my only other suggestion would be to switch Flash to "click to play" so that you can control when it is used.

You can do that on the Add-ons page. Either:

• Ctrl+Shift+a
• orange Firefox button (or Tools menu) > Add-ons

In the left column, click Plugins. Then set Shockwave Flash to "Ask to Activate". On sites that use Flash, any visible Flash region should get a click to play message, or you can use the "Lego-like" icon that will appear in the address bar.

* Mitigations:

(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

(A) In Firefox, un-check the box here and restart:

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

(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

(3) Disable the protected mode feature of the Flash Player plugin (Windows Vista and higher)

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

I'll keep you posted and thanks alot j2000 !

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

I did 2 things which so far are working:

1. In the left column, click Plugins. Then set Shockwave Flash to "Ask to Activate".

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

I found a solution to the flash player crashes within Firefox, and have not had a single flash playser crash in 6 months at least. The solution involves creating a task to run at regular intervals to delete certain prefetch files. NOT all of them as it is NOT necessary to delete them all.

I have wrote a script that will create the folder structer in programdata/scripts/ and place the exe that actually does the deleting, and have successfully imported the task into task scheduler.

This should resolve all Flash player crashes within Firefox. I posted the information here: https://support.mozilla.org/en-US/questions/968190?page=6#answer-51113 2

That script is not 100% Automated in the above link, but will get you started.

I have one that i have been able to fully automate, You would just need to check task scheduler in Windows 7 to confirm it will successfully import on its own.

I am looking for testers to confirm this works. This should work on windows 7 64 and 32 bit. Not tested on Windows 8
