We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) 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.

Does it still happen in Troubleshoot Mode?

There were no crash reports and as of asking the question, no tabs have crashed again. If the tab crash happens again I will look for a crash report and try Toubleshoot mode.

Hello,

I have been "tab crash" free since May 1, 2024 up until today (May 6, 2024). When the crash happened, I went to about:crashes and there is only one crash report from 11/24/2023.

I believe this tab-crashing is closely related to my business bank's website and Quickbooks online. I had both of these tabs opened and both tabs crashed. The bank tab restored itself while the Quickbooks tab stayed on the "tab-crash" web page.

I have multiple Firefox windows open with multiple tabs opened in each. I found this article: https://support.mozilla.org/en-US/questions/1159697 and have now set these preferences to false through about:config: browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false. But another Firefox article says this will have no effect.

We'll have to see if that works.

Thanks
