Hello, I use Firefox on Windows 11 . Since my computer became so slow, I checked task manager and found that Firefox is eating up my memory. It is described as Firefox(35) and is using about 2690MB. I would like to know how to reduce memory use if possible. Best regards.

You can find the current multi-process state on the Troubleshooting Information page (about:support).

  • "Help -> Troubleshooting Information"
    "Application Basics":<be>Multiprocess Windows and Fission Windows
    "Remote Processes" (Web Content)

You can check the about:memory and about:processes pages for info about all processes. There are several toolkit.aboutProcesses prefs on the about:config page to show more info. See also the about:unloads page for info about the tabs.

You can possibly modify this pref on the about:config page.

You can try an extension like Auto Tab Discard.
