unfortunately those crash reports haven't been submitted.

If a line on the about:crashes page doesn't start with "bp-" then you can 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

• https://support.mozilla.org/en-US/kb/Mozilla+Crash+Reporter

Try to start Firefox in Safe Mode to see if that works.

• Windows: hold down the Shift key while starting Firefox
• Mac: hold down the Options key while starting Firefox

• https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Try to start Firefox with the about:blank page by creating a copy of the current Firefox desktop shortcut. Add a space and -url "about:blank" to the target field in the Properties.

Oh right, sorry about that. I have since started submitting every crash report.

I did try starting in safe-mode and it still ends up crashing. It doesn't always crash on start-up, only sometimes... I'm not sure how to isolate the issue.

I'll try the about:blank page.

Thanks for your help, I really appreciate it.

Please post the new crash reports, for the last 3 days only. Be sure the have bp- in front of the numbers/letters.

Dropbox? Okay, i'll uninstall/reinstall, then do the system file check.

Thanks!

Uninstalled/Reinstalled Dropbox.

Ran the system file check, and "Windows Resource Protection did not find any integrity violations."

I'll keep an eye out for more crashes and let you know if they come. Thank you for the help!

Please post any new crashes.

Edit:

Could this be related to Bitdefender by chance? I was having an issue installing/uninstalling it and it's still lingering causing problems. I think I might reinstall windows soon, that could fix the issues.
