Firefox, and the Mozilla organization itself, has its own fair share of issues.

I really wish more people would look at and help develop NetSurf[0] or other lightweight browsers with their own layout engines More importantly, I wish that regular users would stop going with the 900 pound Chromium/Blink gorilla, and instead use a greater variety of browsers/engines. This browser monoculture is just pure death.

It will need Windows support to gain any real traction.

I've had decent luck with Vivaldi lately.

Please note, that it is Chromium based as well.

Do other Chromium based browsers like Brave count? Or do they need be completely separate browser architectures like Firefox and Opera?

Opera uses Chromium nowadays.

Why not use Edge if you need to use a chromium based browser?

I refuse to use it out of spite in response to how hard Microsoft has tried to force Edge down everyone's throat: resetting the default to Edge after a windows update, making start menu searches go to edge regardless of the default browser, etc.

It's like Chrome, but better in pretty much every way. Never thought I'd say this but Edge is actually pretty good!

Very frequent and large feature updates, deepening ecosystem integration that uncharacteristically doesn't get the way if you don't use it.

I always get a bit anxious when one of these massive enterprises suddenly gets up and starts moving with newfound focus, and MS is pretty much sprinting on Adderall at this point.

I use edge on Windows and it never gets in the way like Chrome. No annoyance whatsoever and felt zippier too

Unfortunately on Mac, I have to run some JS heavy apps and Firefox's performance on those is dismal. Jetstream benchmark for Chrome is 102 vs Firefox at 65.
