not the real ublock any way
Given what happened after the previous ublock splitt iam hesitant to use it.
I really haven't experienced this at all. Up until about a month ago when they pushed a big update, Safari has been my problem child browser. IE Edge has been really solid with conformance. Looking at compliance to the html5 spec, edge is neck and neck with firefox: https://html5test.com/results/desktop.html
Disclaimer: I used to work for ms, but not on edge.
Comparing the last version of IE, the latest Edge and, the latest Chrome: https://html5test.com/compare/browser/ie-11/edge-12/edge-15/... it looks like it's catching up and implementing a lot of important APIs.
As far as I know, Edge is a little slow to adopt new stuff, perhaps because they're afraid of implementing something and having everyone scream "Embrace, Extend, Extinguish!" at them.
The specific cases I've had are with how SVG's are rendered and that manipulating them with css does not work in-document like it does in Chrome or Firefox.
The bugs page itself isn't very insightful, but if you look at the issues posted, you'l see that there is significantly less conversation or involvement of people into the problems. By itself, Edge not being open source should make it unfit for usage, but they also don't involve themselves nearly as much in the web community. This is one big factor why chrome gets more vulnerability reports than Edge.
