*Second edit* Issue seems resolved as of early April 2020. No idea what changed and I don't care hehe. Back to a 5/5 for me. *edit*

This add on is great, but it has a very annoying flaw. It randomly stop working (with some frequency), forcing me to go into the addon configuration and disable/re-enable it to get it to work again. It does exactly what it says it will do, which is awesome, but this erratic behaviour keeps it a 3/5 for me.

*first edit* I can't figure out how to reply, so I'll edit here. Interference may be coming from one of two add-ons I have: 1) uBlock Origin and 2) Video Background Play Fix. Of the two, background play seems more likely, but who knows. Unfortunately, I need those add-ons more than this one, so I'll just live with enabling / disabling for now. Also, I just assumed this was a Firefox for Android reporting / reviewing system, but it seems it isn't. Because I didn't mention it before, I'm running Android 9 on a Samsung A8 (2018). *edit*
