Kiwi Browser alternatives with extension support

Comparison vs Kiwi Browser, YMMV:

Lemur/Quetta/Rainsee/Kito - shady closed sourced Chinese browsers not even worth checking out (same goes for Russian Yandex)

Edge Canary - about same speed as Kiwi, sometimes crashing, bottom navbar wasting space, tons of wasted space on homepage with 9 shortcuts allowed, needs to install extensions through Developer options, whole UI is mess, bad tab switcher (using list, grid unusable)

Firefox Nightly - faster than Kiwi, crashing/freezing quite often, lot of wasted space on homepage with 8 shortcuts allowed, bad tab switcher

Mull browser - pretty much same as Firefox Nightly just with some tracking removed

Iceraven browser - faster than Kiwi, didn't try long enough to check crashing/freezing, allows 16+ (4x4) shortcuts on homepage without much space wasted, bad tab switcher (using list, grid unusable), more customization options than Firefox

So I guess after trying Firefox Nightly for few weeks I will give a try to Iceraven, Edge Canary has even worse UI than Firefox and that's something...
