Please, do you think that I ask for help before reading this page? I've been here. Posting my crash reports was supposed to provide with an individual response to my crash problem, not this generic page. Thanks

Crash reports are sent to the Mozilla servers for the techs to look over.
They seldom contact the user.

When you give us the report numbers, we look up the reports
and try to help you fix the issue.
