Firefox uses much memory and many computes > black screen|crashes


(Core :: Performance, defect)

Firefox 107





(Reporter: iappstore, Unassigned, NeedInfo)

Attached file memory-report.json.gz

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:107.0) Gecko/20100101 Firefox/107.0

Steps to reproduce:

Opened many windows and tabs and let FF run for hours or several days.

Actual results:

FF uses much memory and many computes and fills up disk space (low disk error received from W10). Many times, seemingly as a result, the screen goes black and the system freezes for 30 sec or more. Sometimes it comes back, sometimes it hands. Sometimes BSOD.

Expected results:

None of the actual results should have occurred.
