@fribbledom It's so fucking annoying. Why they can't just put a memory limit in those things like any user-respecting app, I cannot fathom.
I'm only ever looking at a handful of tabs at the same time, for heaven's sake!
Firefox is particularly bad (can't say for other browsers) because they don't garbage-collect closed tabs. Not even when you _tell it to optimize_ on about memory! 🤬 It just keeps growing and growing until system memory is full -- and not even _then_ does it give way! AAARG!
@OmegaPolice
Try this extension: https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/
Firefox does some of it itself so I've never seen it grow indefinitely, but this one limits it further. I've configured it to only allow five tabs to remain active — probably not for everyone, but it works for me!
@fribbledom
@m0xee @fribbledom Is that different from "tab unloading"? 'Cause I already do that.
Simple observation: System memory 90% full. Close FF, open FF. Same tabs; fewer loaded, of course. Observable effect similar to OP. Then, over several days, usage grows.
I once found an issue comment stating that, indeed, they consider this a _feature_! Idle memory doesn't help anybody, after all, right? Better use it for good! Maybe I visit the same random page again this year! You never know! /s
@m0xee @fribbledom (That's me assuming they don't just have a straight-up memory leak.)
I _sort of_ follow the reasoning -- if they would ever release all that memory when it's needed. But nope. Restarting FF consistently brings back 10GB RAM (-ish) but, somehow, opening a second Miro board can freeze my entire machine.
Miro is a true memory sinner btw. Really, really awful. An empty board starts somewhere around 500GB, if I can trust FF to show meaningful numbers.
@OmegaPolice
Yes, it uses tab unloading, it just gives you more customisation and fine-grained control over it. I have to admit, I don't open many "heavy" website — could be the real reason I never experience these leaks, but the machine I'm typing this on is decade-old laptop with only 16 gigs of RAM, it has an uptime of over a month, I'm not certain that Firefox kept running the entire time though, but it currently has about two dozens of open tabs, most of which are unloaded and…

…it uses just about half a gigabyte of real RAM (resident, virtual memory allocated is still above 4 Gb of course) — as you can see, it's very modest, Thunderbird consumes more even when idle, and software based on webkit-gtk can consume about 2 Gb easily just after opening a couple of pages. I'm using Firefox in Void Linux and I stopped updating it at FF124 — could also be the reason why it's different here.
@m0xee The main different seems to be the sheer number of open (if unloaded) tabs I have. There are several dozen "resident" tabs at least, some of those huge-ass apps. 😅 I also create _many_ ephemeral tabs, probably hundreds each day.
For some reason, Firefox keeps data of unloaded and even _closed_ tabs in memory; at least that's the only explanation I can come up with for what I'm seeing.
I'll give that plugin a shot, thanks for the pointer!
I currently rely on the unloader addon of TabTree
@OmegaPolice
I don't remember experiencing these insane leaks for quite some time already and AutoTabDiscard usually helps freeing lots of RAM, no need for a complete restart.
