If you figured out how to use good extensions, you're probably on firefox anyways. The chrome extensions suck ass. Wtf is this privacy reader thing use Dark Background and Light Text. Most of them use adblock pro or something and not ublock. Chrome doesn't even have good vertical tab extensions.
It's nice to see another Android browser follow Mozilla's steps and implement extensions. Though I strongly doubt Google is ever going to follow. Chrome not having extensions (or an ad blocker, at minimum with history and bookmark synchronization) on mobile is the main reason I don't use it anywhere.
Personally, I've been asking for this for years. Very excited to see this mostly for ublock origin. But there are a few other extensions I use daily that I'd like to have available.
Why use Edge tho? If you want a browser on Android with extensions, just use Firefox. In my humble opinion: M$ anything should be avoided (unless there are specific benefits or features).
