"My only gripe is filling in card details, there is never a floating icon to click to do it automatically, you need to go to the menu bar and select the card."

"My only gripe is filling in card details, there is never a floating icon to click to do it automatically, you need to go to the menu bar and select the card." At one point I became convinced that this is actually a security feature. If I recall, an article demonstrated tricking users into entering their master password using those "in-browser" decorations. I could write some html/js to build your password manager icon/etc and trick you into thinking I'm your password manager? I now accept it as a necessary UX chore to leave the browser page, but would be interested in being wrong.
