Trying out WebLibre browser right now and really like it. Based on Gecko engine. There's some unnecessary ~ "AI" ~ (opt-in) but a few features make it worth it.
- Real rules for tab containers. There's even automatic isolation and baked-in tor per container, and easy per URI rules
- Real plugins. ublock origin out of the box, even an option to force enable desktop Firefox plugins if you choose.
- Real PWA support. There's an option to force add sites as a PWA even if the site doesn't officially support it. On grapheneos it means I don't need NativeAlpha to make my tiny bank's site appear as a PWA.
