Does anyone have this issue were firefox becomes slow if left open for a long time. In my case after a couple of weeks rendering becomes slow and when I use youtube for example if is laggy, just trying to change volume taka few second to show the volume bar. It also happens to my laptop at work. I have around 30 tabs open.

I've got more than 30 open tabs, though in practice I don't actually need ALL those tabs loaded. The extension unloads inactive tabs after a configurable time. You can also configure the extension so that pinned tabs are not unloaded, certain domains/URL patterns are not unloaded, etc.

FFS, his leak is probably in an extension.

Installing more extensions that might also leak is not a real solution, no matter what they do.

Firefox can automatically discard tabs when available memory gets too short. You need to configure it to do that though and probably disable the 10min minimum open time too if you're very short on memory.

That's a healthy solution
