Colif :
Wonder how many on insider preview report bugs as opposed to just using it as a sort of early access (Note: before anyone attacks me, I realise not all are like this but I can guess there is a fair percentage).
I haven't got it yet and am sitting here seeing all the fun bugs I might have to deal with. I was unlikely to use Edge anyway as it only has so many Add ons and doesn't have Ublock Origin yet, just Ad Block Plus that already lets ads through if you pay them enough. Pass.
Google Chrome's Adblock is robust. For the other browsers? Not so much.
I should add a solved to the first post. It's unintuitive design that caused the issue.
Chrome puts your bookmarks up top, and they are also accessible in the only Menu Chrome has (outside of File Edit etc)
In Edge, you need to click the three lines that looks like a list and the bookmarks are in there. The bookmarks bar doesn't tell you that though. It also doesn't tell you that to add stuff to it, I think you need to do it on a per-bookmark basis (like how you have the Other bookmarks folder in Chrome)
Edge's method of determining what page you were last on seems hit or miss. In Chrome, when I press the back navigation button on my mouse it goes back 1 page (vice versa for going forward). Edge, it will do that most time, but then it will start registering as a double tap. Same issue with the Xbox One controller in Steam. The 360 controller is unaffected
I'm only trying Edge, because it got updated.
Also, Ask Cortana is not universal. You can right click in Edge and have Ask Cortana for a definition. So far I haven't seen it work in other places, will have to try some more. It should be universal like OSX three finger tap
