In firefox you can see which pages and addons use the memory on the about:processes page, shortcut is shift+esc.

Rookie numbers!

I never understand why people upset about processes using ram. It's there to be used. If it's not being used then things are not being cached properly.

Now, if there are other higher priority processes and the browser doesn't give back the tam, that's different. From your screenshot, why wouldn't you want it using the ram? Otherwise it'll cache to disk and you'll have a worse experience.

Unused ram is wasted ram!

I once had an empty konsole take 3gb of ram one time.

You guys have RAM?? I just zram to my 20GB ATA HDD and a 4GB SD card.

(but current horrors aside - you are fine imho, FF can show you usage per page, and that's prob cache with no CPU usage, super dependant on what the opened pages are)

Go to about:performance and find why.

It may only be reserving that memory, but not actually using it yet.

9 tabs 2 windows 8 extensions

Librewolf is using around 200mb of memory with 19 tabs open. What the hell is Firefox doing?

Install tab suspender extension.

Tabs will release memory after a set amount of time.
