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.

If it's related to the thread you posted then try Nightly?

That's only in Nightly right now, unfortunately; it won't make it out to Release until v134.

Also, can I ask why you'd leave your browser open for weeks? Just curious of the use case. The thread mentions having 5700-7000 open tabs, and I can't fathom why someone would do that. It's not like the websites disappear if you close the tab. Nothing to do with the problem though, you don't have to answer.

some people use tabs as bookmarks 🤷

This just begs the question, Why do you not leave it open?

To conserve resources / power? Like when I'm done using an app, I close it. When I'm done reading a website or using online banking, I close it. I don't leave my email, games or music open after I'm doing using them either. I actually turn off / sleep my entire device when I'm done using it, but that's not what my curiosity is about.

Sure. Personally I just close the tabs, tho.

I only have around 30 open and I don't turn off the laptop, after a while firefox becomes sluggish and I have to restart it.

Have you tested with specific websites? Could it be a tab has some have JavaScript running constantly that’s causing the issue?

I haven't tested it at my home laptops, but my work laptop all tabs become slow. I have to restart it every time.

You should try that nightly build for troubleshooting purposes

Also, because it forces you to restart the browser every night.
