Firefox

I'm not talking about an extra 10-15sec, but easily 2-3 full minutes (I've sat here with a timer checking) to load pages, sometimes not loading them at all. Particularly with login pages, but even just homepages.

Dropbox, Cloudflare, Various companies forums, My bank, Google; each of these sites and more I've had firefox either not load at all, or take so long I've been able to copy the link into Chrome, do what I need there, then come back to Firefox still 'loading' a blank white page.

I just don't understand. I want to migrate away from Chrome and use Firefox, but it's been unusably slow when it even loads anything at all.

P.S. In the time I've taken to write this (~5min) plus the time to decide to post and find this community firefox has still not loaded my cloudflare dash... (typed in the address, waited a while, gave up and came here but left it open)

/edit: I should note I have ublock installed, but I get the same results with it disabled most of the time.
