I'm so grateful that FF for Android exists with addon support. Using it with uBlock is the only way to make mobile not an awful experience for me.
I wish I could switch to FF, but I still need PWA support + rich media notifications for a web based music player I wrote.

The Einkbro browser, optimised for e-ink devices (as the name suggests) is one. I believe Brave does as well.
As much as I'm a fan of Firefox (using it now on desktop), on my mobile e-ink device, Einkbro's optimisations make for a vastly superior browsing experience.
