TIL someone uses Firefox for Android. I'd personally use it if it was at least half good as their desktop version. It's just too resource hungry and lacks of features/settings desktop variant has. Because of this I'm forced to use Brave.
Firefox subreddit is riddled with questions like this:
Mozilla might (or might not) stop supporting MV2 API some time in the future, so you're now using uBO Lite and worsening your ad block experience to be prepared for the future?
This doesn't make sense because Mozilla doesn't even have a roadmap when will they stop supporting MV2 what tells us it's not their plan for at least the next 5 years. Beside, they could always make an exception for already created verified extensions and limit the unverified and new ones to MV3. Something Google refused to do.
