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.
Listen, not even Dexter is the kind of person to leave thirty tabs open for two weeks. You would have to be some kind of insane serial killer to do stuff like that.
I currently have a bit over 2400 tabs open, and it has been roughly a month since I restarted firefox for being too laggy. It is becoming an issue again.
