It’s weird, this is presented as new, but I had adblock on Firefox on Android from the start.
That and flash support were two of the major reasons for using Firefox on Android in the first place. This was back around 2010, when most porn sites still used flash players for video. Then flash died, that was fine. Then at some point Mozilla reduced the available extensions a lot, but at least some adblocker was still available.
They only allow a handful of curated extensions on mobile. You’ll have to use the nightly build and jump through some hoops to install arbitrary extensions on mobile (mostly to allow devs to test their extension). Looks like they’ll finally lift the restriction soon.
They rebuilt the mobile browser, if I’m not mistaken. It’s why the extensions stopped for a long time.
