Yeah the problem is not the browser, it’s that websites are so big. Firefox works perfectly fine on low bandwidth if you use ublock origin and block media and script loading.
I use this often for the same reason, many websites don’t display properly or at all anymore but at least it’s more usable.





That’s what you think, but as soon as I leave this comment thread and become unaware of it, I’m sorry to say, but you will stop existing. Tough luck.
