Edge isn't great period. There are too many janky UI and design choices - probably because it is part of that whole benighted Metro ecosystem.

The thing that really drove me nuts was how the address bar jumps around when you're trying to select part of a URL, which makes it so much harder than it ought to be when you are trying to click and drag with a mouse, let alone a touch interface.

Agree completely. I'm a heavy Windows/Office/.NET/F#/Powershell user, overall a fan of MS ecosystem, but Edge is still just plain painful to actually use day to day. Chrome remains far ahead. I'd say "1000 papercuts" but maybe 5-10k is closer.

Jumping address bar? Ohhhh yeah hate that one: https://twitter.com/LincolnAtkinson/status/88703561300998963...

One thing that catches me surprisingly often when I use Edge (which is very, very rarely, contributing to this), is that all the browser controls, like Back, stay in focus when you click them until you click something else. I don't think any other common browser has this behaviour, which is why I'm not used to un-focusing them, and the next press of space definitely does something I did not intend it to do.

Exactly this. I lose my open tabs every 2 weeks or so. I've reported this to the black hole of Edge feedback on numerous occasions. How hard can this be to get right?
