I’ve seen FFUpdater recommended a couple of times, but I’m unsure why you would need this updater if youve installed your browser from F-droid and update your apps regularly. Does FFUpdater do anything special?
F-droid is a bit slow rolling out updates as they recompile everything themselves. The only reason to use ffupdater would be to speed it up, I suppose.
I just installed it to have a look for myself - there are a couple of browsers available to download through FFUpdater, that aren’t available from F-droid (Iceraven and bromite, maybe others too, I didn’t check them all), so that’s another reason for installing FFUpdater, if you want to try those.
You can use Obtanium for some (maybe all?) Of those. Whatever you prefer!
You get the latest release straight from the source, best benefit
