Crashes or other problems with certain multimedia content in Firefox (such as Youtube videos and Flash animations or games) can often be resolved by performing the steps in these Knowledge Base articles:

• Flash Plugin - Keep it up to date and troubleshoot problems

• Adobe Flash plugin has crashed - Prevent it from happening again

• Flash 11.3 doesn't load video in Firefox

On Windows Vista and above, you can disable Flash protected mode by following the instructions on these pages:

(See this Adobe blog post for technical details about Flash protected mode.)

Please tell us if this helped!

We're sorry to hear that Firefox is crashing. Please provide the Crash Report ID's so that we can view those reports.

1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste that into the "Post a Reply" box. (Please don't take a screenshot of your crashes, just copy and paste the ID's. The below image is just an example of what your Firefox screen should look like)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

None start with BP but here are a string of them

Hi userSharonD, the ID should switch to having a bp- if you click each report number to submit the associated data.

Here you go. bp-252f38ce-c479-481d-96ab-2c0532140825 8/23/2014 11:34 PM bp-12d4c4ba-41f0-497e-b70a-71d5c2140825 8/23/2014 11:34 PM bp-17d3d8fc-aaf5-4f53-864f-f873f2140825 8/23/2014 11:33 PM bp-02c4ec1d-bf89-4fe3-b80b-c78592140825 8/23/2014 11:32 PM bp-fbd8c7d3-9284-415f-a998-9fe452140825 8/23/2014 11:32 PM

Also, I reverted back to Adobe Flashplayer 10.3.183.90 as that is the only one I can get to work without it crashing. Any version beyond that gives me issues.

Hi userSharonD, if Flash newer than Flash 11.2 causes problems, there's a good chance that is due to the protected mode feature added in Flash 11.3. It has security benefits, but is not compatible with all systems for some reason.

You can disable the feature by creating or editing a settings file. The following pages/posts provide different ways to do that:

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

• Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209

• Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078

Flash needs to completely unload from memory (exiting and starting Firefox up again might help) before this takes effect.
