Not quite in the context of the op's thread title, but this might interest users. I use edge fairly regularly, I have a very slow connection, and I find FF and Chrome too heavy on resource. Bottom lineis, I would suggest, quoting another thread, it is all a matter of where you find your "comfort zone"
From a testing site:
"
Using Edge is a perfectly pleasant experience. It's super-quick, hammers through benchmarks, its integrated reading mode makes complex sites more palatable, and by sandboxing it away from the rest of the operating system Microsoft has ensured that Edge won't suffer the security breaches of its older brother."
"
I have, in the past, tried Opera and, for reasons which I have forgotten, returned to the more popular browsers. But, which the latest releases, I might give it another try.
I needed to return to add:
OK. So I installed Opera and quickly ran through the setup. Maybe I need to work with it a little, but I was shocked by the amount of memory it consumed (240MBs) about four times more than Edge o rIE (The lowest) I'll keep trying for a couple of days, then, if no improvement, its gone.
