Stop paying the CEO so much!
Firefox could by now have:
- Much better anti-fingerprinting for a generalized threat model (RFP is too specialized for anonymity)
- Fission (per-site process isolation) for Android, among other things.
- Integrated content blocking (based on uBlock but with the development power of Mozilla)
- Tab groups ffs
- Native force dark mode for web pages
- Sandboxing support using zypak fork server for Flatpak (currently Flatpak weakens Firefox isolation substantially)
- UI/UX update (hire the talent at Zen browser)
I would avoid /e/os (and iode) because they are frequently behind on Android security patches. More information here: https://divestos.org/pages/patch_history
