I was using 3 Firefox browser tabs and it just decided to use 4 gigabytes of memory

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

thanks friend.

What was the culprit?

Also this is a kind of joke/meme community on IT topics, questions like these should go to !techsupport@lemmy.world

Except if it's your gentoo box running on live rat brain, and your problem is why it uses 3 bytes more than it should. For questions like that this is the correct community.

See? Webbrowsers are now their own operating systems.

sorry friend, lately browsers have been very heavy and I used Firefox because it is light, so now nothing is more meaningful

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

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.

your argument seems right, you have a good point

You guys have RAM?? I just zram to my 20GB ATA HDD.

(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)

Install tab suspender extension.

Tabs will release memory after a set amount of time.

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

What's your config? Mine is 200 with no tabs open

Edit: is it because I'm using the flatpak?

Depends on the total amount, they might have 16GB total then it is, they might have 128GB then not so much 😅
