Why is my Mozilla Firefox so slow?

Anyway, one potential issue is Flash. Firefox seems to die quite easily due to Flash, and especially some video/streaming services using Flash seem to have a memory leak in Firefox. Twitch, for example, seems to leak memory for me on Firefox, which makes everything unbearably slow after an hour or so. If you have a lot of Flash tabs open, it's almost certainly causing problems for you. Have you checked how much your Firefox is using RAM? From the Task Manager?

It's certainly a huge amount of stuff, and yes it's gonna take ages lol

I have checked RAM usage from Task manager and it's not much. Usually something like 3.5 GBs. So maybe it has more to do with Flash usage like you describe?

 

You're using Flash in more tabs than you can keep track of?  And you haven't restarted since at least August?  There's already been 3 critical vulnerabilities in Flash disclosed since September, and you haven't restarted your browser.  When's the last time you updated Flash?  You seem to be asking for a virus.
