Its tab management / display is also vastly superior to Chrome's.
Firefox/Android (or Fennec via F-Droid) has some annoyances:
- No keyboard hotkeys.
- Doesn't full-screen maximise.
- No print-to-PDF.
- No per-site font or zoom settings.
- No per-site cookie management.
- Weak Bookmarks controls (bookmarks cannot be reordered once saved).
For a mobile browser, though, it's pretty good. Far superior to Chrome IMO, except on older devices where there's still a noticeable performance penalty (a 2015-era Samsung tablet).
There are mobile browsers which support this (Firefox notably), and mobile-device adblock apps as well, in the event you're not on a desktop system.
If you're in a corporate environment, put in a request for adblock on your network as, amongst other things, a security feature:
