TBird will have issues with flash. At least they have a menu bar.
I can't stand Chrome. Miss google groups. Anything and everything needs to be done with hotkeys.
Edge is the next developers challenge and how well they can dumb it down.
The leaves IE. For whatever reason the above browsers you can create shortcuts to web pages on desktop. FF can with an extension. As for Chrome - who cares? Edge you can open one made with IE.
I like my webpage shortcuts. I put them in folders if I need to on the desktop. I use Roboform which also means browser limitations. Sorry nothing comes close to Roboform either.
Despite all of the negatives about IE I might go back to it if the browsers keep changing by having less features. I have no clue how people can operate dumbed down less featured browsers on phones.
I don't get the less functionality on a browser. They all suck to some major degree. Soon FF will change and Roboform users will not have that sweet functionality and be as annoying as Chrome. Developers seem to live in their own world these days and have no clue how a human functions. See Frys Food phone apps. Developers (outside of the DAW world) are on the list of denying parachutes next to politicians.
