Yahoo Mail doesn't work in Internet Explore anymore. They made stupid updates so now you can only use it in Edge. The old Yahoo Mail was better and faster.
Arutz 7 has been going ape in Internet Explorer for years. I thought it just didn't work good or crashed too much. But it works fine in Edge.
Internet Explorer is a better browser but many websites don't work in it. Upgrades aren't really upgrades. They just make things too advanced. A site like JTF's Forum, the main Google site, and many simple text sites load instantly on Internet Explorer. Many features of Internet Explorer are better including left click so you can see the URL of an image and include it on the forum. Newer sites allow you to copy and paste pictures without the URL. You can cut and paste from one place to the other and includes the same font and images. Sometimes that's good. Other times it's not. It's not good when you are writing something and want to paste and then it messes up the text of where you are writing. A way to get around that is it to paste it onto a forum like JTF where you type and then cut and paste it a second time from the forum and then it's just regular text.
