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.
Come on 30 tabs is nothing, read the bug report. The guy in the bug report open about a 1000 in totals, I don’t even know how to keep up with that many tabs.
