1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. 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.

. . . firefox reloads a tab when i move back to it after having gone to another tab - restarting videos

I get around this by; When I find a link I want to check out, I open it in a new tab/window. Then when I am done, I close it and am back where I started.

. . . also i am getting dialogue boxes stating the i have run out of memory; also my vpn stopped connecting. i have reinstalled firefox

Did you do a clean re-install?

Firefox will now detect if your computer’s memory is running low, which is defined as lower than 400MB, and suspend unused tabs that you haven’t used or looked at in a while. The new tab unload feature is controlled on the about:config page with a preference that you can set to false to disable this feature.

• browser.tabs.unloadOnLowMemory = false

Are these crashes caused by out-of-memory (OOM) issues where not enough contiguous free memory is available?
