I didn't even realise it worked on mobile, I use uBlock on Android but uMatrix otherwise (actually I think both, maybe because of synchronisation).
The zapper's fairly easy to use to get rid of annoyances on mobile, until you make a mistake. Editing the rules file isn't the nicest UX even on desktop FF. (It'd be good, for example, to be able to preview what's being blocked, and selectively re-allow them.)
For an example of how it can go wrong: you block 'overlay', then it reveals and you block 'grey-blur-modal-focus', allowing you to click whatever you wanted, except it turns out that it uses 'overlay' and you shouldn't have blocked that one.
