Observing memory usage while Firefox is in safe mode may help tell you whether one of your extensions or themes is causing memory problems.
Memory troubleshooting tools
Firefox developers have written two extensions to help users isolate leak bugs:
- Leak Monitor : Can alert you immediately when certain types of leaks occur. This makes it easier to figure out what triggers these leaks.
- RAMBack: Lets you flush many of Firefox's caches, allowing you to distinguish caching from leaking.
