funny thing: firefox is using ~433mb of ram with ~15 tabs (including gmail, graphql playground, youtube).

slack alone is using 300mb. discord is using another 300mb.

Just curious, how many extensions do you have? I'm trying not to bloat my browser too much with them, but have 3-4 privacy related extensions and a couple of utility ones. Right now I have 22 tabs and Firefox uses 5-6 GB of RAM. Restart decreases RAM usage, but Firefox slowly eats RAM again.

I remember recently I freed 10GB of RAM just by restarting Firefox. I literally looked at Ubuntu's System Monitor. And I keep everything updated.

Tried to play with settings in about:config, made even worse and reset.

i'm using firefox nightly, with just a handful of extensions. vim vixen, lastpass, ublock origin and simple tab groups.

that's on linux, latest nightly.

I just checked mine my slack because I thought 300mb was too low for slack, mine is using 68mb, it used to chew like 1gb... Did they optimize it or something.

No optimisations here: Slack is using VIRT: 24.868g, RSS: 1.919g, SHR: 526924

Next highest single process is Firefox with 1G RSS and 5G Virt. I have 113 tabs open at the moment, although there's about 4G of RSS in "Web Content" processes which are firefox related.
