I know uMatrix development has been abandoned for quite a while now [0].  But, at least up until quite recently, it continued to work on my Android browsers of choice [Yandex & Kiwi]. This is, sadly, no longer true. uMatrix on Android now has completely stopped working. It just greys out the screen. No interface appears.So, is there a worthy alternative or one of the several hundred forks in particular around which most further development is coalescing?[0]  uMatrix continues to work for me on desktop [for now!] It's just on mobile it seems to have recently broken. So presumably a recent change in Chrome for Android [upon which both Yandex and Kiwi are based] has knackered it.
