3-4 times in the past week, Firefox alerted me that it has crashed--I never noticed anything unusual. Is this leg?
In the address bar, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.
The crash report is several pages of data. We need the report numbers to see the whole report.
Using your mouse, mark the most recent 7 - 10 Submitted crash reports, and copy them. Now go to the reply box and paste them in.
Please, Do not post a screenshot ! !
