I haven’t had it hang yet but it does slow down and become laggy after a week or so for me.

You can use “Open previous Windows and tabs” to keep your tabs between restarts. It only works on the last window you have closed though.

Same for me. I discovered it was Slack that had some live leak, one time it had eaten 33GB of RAM. An auto-reload extesion did the trick to prevent it from going too far, but I'd really wish Firefox would handle it more gracefully.

Unless I say so, a normal web page shouldn't eat gigs of RAM or tons of CPU.

So wouldn't chrome have the same issue?

I do have similar problems with chrome and have to restart it every few days.

And Safari on MacOS. It occasionally gets into a state where it becomes unresponsive to clicking on links.

I noticed a similar problem with Twitch client.

Given how well web pages are coded, I'm curious whether a Firefox that's browsed to 50 static pages fares. At some point the pages themselves should get some blame (and yes, they can be offloaded, but we're back to balancing responsiveness & long term resource usage, and people are complaining about the pages being reloaded after exit as a delay)

Chrome recently added a setting so you can display a tab’s memory usage when you mouse over the tab. In Firefox, you can check the memory usage of each tab in Firefox’s Task Manager (about:processes).

Or use the much more detailed about:memory, that's how I discovered the live leak.

Alt+F, Q exits all windows at once and also restores them the next time you launch firefox.

Ctrl+Q or Cmd+Q for Mac.

Or Exit under the hamburger menu, if you don't want to remember the keyboard shortcut.

It will work on all open windows if you close them at the same time. File->Quit, ctrl+q or cmd+q are all ways to do that.

Yeah it does the same for me (macos) after a few days. Open previous windows and tabs should restore all windows though (at least it does for me).
