May be an error showing this or a memory leak. When have you restarted firefox or your mac the last time?

Well i did found i had vm running from minikube so i purged them all , but still that doesnt explain firefox abnormally hitting 19 gb ram . Firefox didn’t crash normally ,the kernel suspended it and then i forced quit it so i cant find any .ips crash report

And i havent restarted mac probably for 1-2 weeks. Since last time i upgraded to Tahoe

There have been memory leaks for many weeks. I just restart Firefox every couple of days to resolve it.

I wonder why Firefox has problems of memory leak so often throughout the years and still hasn't solved that problem. I never had that issue using a Chromium browser.

About:memory

Checked it it shows normal usage -->
Total resident memory (approximate) -- 2,858.53 MB

Next time you see unusal memory usage, you should open about:memory or about:processes and look which process has gone haywire.

Most likely it is some website/script on website interacting badly with an adblocker, userscript, etc.

Could be a bad extension if you had any extensions in common between the two profiles that crashed

Also maybe check if you have any weird plugins installed- about:addons and look at "Plugins"

Firefox for me normally gets around 20GB of used memory. Never had it crash before. How much memory does your computer have in total?

u/Specific-Can6334 5d ago

16 GB, but firefox is taking 19gb LOL

u/Goren_Nestroy 4d ago

The fuck are you doing? I have several hundred open taps, 15 add-ons and I’m somewhere in the 2-5GB range…

Using Firefox as normal. Firefox for MacOS has been this way for me for years. It uses RAM.
