Actually, I've been using Edge as my main browser in Linux for the last couple of months. The main reason is that it is the only Chrome based browser that has a good vertical tabs interface integrated. They are pretty good, with grouping, colors and whatnot. I've tried every extension in chrome but nothing comes closer. I also used to use "tree style tabs" back when I used Firefox, but I find Fx unusable nowadays. A combo of vertical-tabs, tabs-suspender and extensity are a winner mix for me in Edge. in Linux!
