I dont know if these are them. I uninstalled firefox and reinstalled

Crash ID: bp-4443c651-10a2-49d3-8ff6-1a49e2150518

Crash ID: bp-bcdbb780-f7af-42be-a2e6-041aa2150423

Don't know if this helps

The crash numbers you posted are no good. Did you follow the posted instructions?

If a line on the about:crashes page doesn't start with "bp-" then click the line to submit the report and the link will be updated and gets a "bp-" prefix if the report is submitted successfully.

• please do not add the "bp-" prefix yourself
