Firefox blacking out and crashing

This has been happening at least three times a day. As per Mozilla's instructions on a page dated last year, I entered about:crash into the browser window. Here are the first five results:

The "bp-" string is the Report ID for the crash report. It is needed if you do a manual upload of the crash report. Details toward the bottom of this page.
