One thing I like about Microsoft Explorer is in Control Panel, under Internet Options one can setup multiple tabs so when the Internet opens, one starts off at multiple websites. Is there a way to do that in Edge, Chrome, or Firefox ?
Yep - in Firefox, click the three horizontal bar icon in the top right, click settings. In the new menu, click on 'Home' on the leftside navigation menu and set 'Homepage and new windows' to Custom URLs.
In Chrome, click the three dots icon in the top right, click settings, and scroll down to the 'On Startup' section. In the bottom of that section you can set the pages to open at start up.
With Edge, I actually don't know because it's really not that great a browser in my opinion. The only time I'll use it is if I'm trying something on a Microsoft site that isn't working in another browser (setting up training for coworkers, getting licenses for software, etc.). If you really want to give it a shot, a google search for 'load custom URLs edge launch,' will probably get you the info.
