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.
Yes it happens. As others have said: just restart.
What might not be as clear: when you restart, if it doesn’t just come up and offer to restore your session, you can go to History and Restore Previous Session. This reopens all your tabs (actually, they won’t fully reload until you view them).
Or just use bookmarks like a normal person
Bookmarks are for really important stuff. Open tabs are for stuff I want to be able to easily stumble back upon, but I won’t be butthurt if I dont.
There’s nothing wrong with having more than one way to categorize stuff.
Edit: and considering that session data is also written to disk, there really isn’t much difference between bookmarks and open tabs anyway.
they have an entirely different use case
