High RAM usage on macOS

Firefox Probleemoplossing
Bithiah beantwoord

Hello,

I have a really high RAM usage with Firefox.

What is intriguing, is, from the "about:performance" tab I totalize 6.02 GiB of RAM. And from the System Monitor, 14.59 GiB (+242.4%).

I suspect a memory leak.

Hey there!

I see that you have went to a similar question in which I have replied recommending the following site to check out: https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources

Have you done so? If you have, I recommend deleting Firefox browser itself and reinstalling it. Hope that works.
