saying Firefox is "better than any other browser on Android" might be true, but it still doesn't make a forced whitelist acceptable. Users should be able to accept the risk and install untrusted addons with a warning. Again, if its an addon that I wrote myself, I should not need Mozilla's approval to install that on my own device.
Also, better than any other browser on Android.
Chrome allows no addons.
Samsung internet and Edge only has Adblock Plus.
Brave, Opera and Vivaldi has its own built-in adblockers.
There is Kiwi browser and Bromite but those where way behind on Chromium versions last I checked.
On android and IOS I would use Brave and/or Firefox.
