I mean, I like Firefox, but I’d love to see Vivaldi based on Firefox/Gecko. There’s Floorp, which is similar in some ways but it’s more like an Edge built on Firefox than Vivaldi.
Edit: Thank y’all for your answers. :D
I want to link !@bdonvr@thelemmy.club 's post because it is a similar quesion. https://thelemmy.club/post/718914
The only time I ever had memory problems with Firefox was when I tried to run it on a potato. That complaint has always been bullshit.
Edit to add: The aforementioned incident was in 2010, on a machine with only 512MB of RAM. Like I said, potato. Chrome back then was somewhat more memory-efficient than Firefox, and could support three open tabs on that machine before it started thrashing, whereas Firefox would thrash with just one. Both browsers performed abysmally under such a severe RAM shortage, but Chrome was slightly less abysmal. Slightly. I seriously doubt the current version of either browser would be usable on that machine, although I don’t have it (I gave it away soon after this incident) so I can’t check.
