Firefox crashes; 4th in last 5 days

more options

Crash does not happen in safe mode. Does crash in regular mode; frequency of crashes is increasing. Occurs when multiple tabs are open (at least 4). Also crashes when multiple instances are open (as a way to avoid multiple open tabs). The following are the first several lines of the last crash report.

Four of the first five on the list indicate OOM Small, which I think means that Firefox exceeded the memory it allocated for a particular task. Unfortunately, the fine details of understanding what Firefox was actually trying to do are hard to extract from the crash reports.

If we work backward from the fact that Firefox does not crash in Safe Mode, the most logical things to try are:

(1) Disable Firefox's use of hardware acceleration, to work around a possible graphics card driver incompatibility:

"3-bar" menu button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

That takes effect the next time you exit and start Firefox back up.

(2) Disable nonessential extensions:

You can do that on the Add-ons page. Either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then, if you can do without it for 24 hours, disable.

(3) If those do not help, try disabling the JavaScript compilers. (I will have to research the steps for that.)

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

I had already disabled hardware acceleration. Now I have disabled ALL add-ons and extensions. I'll give it a week to 10 days to see if anything happens. If all goes well, I'll reactivate one add-on/extension at a time until I get another crash. I'll keep you updated.
