it would randomly start freezing and i’d have to restart it. but when it was running on a fresh start, it was amazing

Weird, that's the exact problem I had on my old desktop and have on my laptop with Firefox. Both were 8gigs of memory and I figured out that the freezing coincided with memory being depleted. My new desktop has, funnily enough, no problems with its 32gigs of memory. I need to purchase a new ram block for my laptop...
