Crash Reason EXCEPTION_BREAKPOINT

Attention Sumo's there are over 60 related bug reports

inproc_agent.dll = Kaspersky Inproc Agent

klsihk64.dll = AO Kaspersky Lab

Update Kaspersky. If the problem continues, disable it.

Hi FreeMcD,

I did what you suggested, but It didn't help. I also reinstalled Firefox - but no Change. I got a new Crash-Report for you:

bp-b52d08f1-2544-4cf2-a2de-dda680181213

What else can you suggest?

Additional Info: After I closed Firefox, there are still 3 processes visible in the Task Manager. While Firefox is running, I got 8 for 2 Windows. Is this normal?

Disable Kaspersky. Is the problem still there? If not, contact Kaspersky support.

Are you using "Clear history when Firefox closes" to clear session data?

Does it has effect if you disable this feature?

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Hi there,

sorry for the late reply but neither the Kapserski - Addon nor any other Plugin / Add-on was the reason. The suggestion with the new profile brought me an idea. I did the following:

1. MozBackup for the whole Profile 2. Delete Cookies and web-site Data: problem still there 3. Deinstallation of Firefox and installation of a new, empty firefox: Problem solved 4. Restore Profile from Backup without Cookies and web-site Data: Problem back 5: Profile deleted again: Problem solved -> something in the profile is causing the Problem 6. Restore without History and General Settings: Problem solved 7. Profile deleted again and restored without History: Problem back 8. Profile deleted again and restored without General Settings: Problem solved

So, finally something in the General Settings was causing the Problem. Hope to help anyone with the detailed solution.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
