Hey! New to mozilla support so sorry if this is a repeat ...

Problem - sometimes the browser window just closes ??

- On Windows 11 with all windows latest updates installed,

- with latest Firefox 115.01 

- all graphics updates installed - all antivirus scans are clean

(Possible it is when doing Windows shortcut keys like ctl-? but I'm not sure.)

When I restart firefox the old tabs/links (history) are not restored making me think it 'closed' and cleared history.

Is there a way to see if this this is 1) an actual browser crash or 2) a log to check for why it closed ?

Thx!

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/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.)
