For Android users seeking a privacy-focused browser, Privacy Guides recommends Mull:
Mull is a privacy oriented and deblobbed Android browser based on Firefox. Compared to Firefox, it offers much greater fingerprinting protection out of the box, and disables JavaScript Just-in-Time (JIT) compilation for enhanced security. It also removes all proprietary elements from Firefox, such as replacing Google Play Services references.
Mull enables many features upstreamed by the Tor uplift project using preferences from Arkenfox. Proprietary blobs are removed from Mozilla's code using the scripts developed for Fennec F-Droid.
Yeah I'm using kiwi browser as my daily driver browser because of extension feature, compared to other chromium based browser.
For firefox, It also has extension feature but the reason why I don't use it because of the auto reload bug and some sites are somehow broken when viewed with firefox mobile.
*But for firefox desktop, I think it's good for me
