I have to look at stuff like this all the time. Sometimes for friends, sometimes because certain applications I use at work behave differently between different browsers. That part is normal.
If I were looking at your issue in person, naturally I'd see if the Big 3 browsers give the same results or not. Just for reference.
Then I'd ask if you were using actual Internet Explorer, or the newer "Edge" browser found in Windows 10. (presumably it's downloadable as well) Naturally, I'd check which version you were on.
Then I'd check your Java version within the Browser, and again via the OS. (Win10, 7, whatever) In the browser, you can find it Internet Options, Programs tab, Manage Add-ons button, then in the window listing "Tools and Extensions". There will be 1 or more Java references there.
For the OS, you can type in Java in Cortana or the Start Menu box and look for 'Configure Java' or Java Console. It will pop up a window and you can then click About, force updates, disable versions if there's more than one, etc.
Not sure what to expect here on my own system as I hate IE, but, I'll try to attach a picture myself as I'm using IE for this post.
Just for you.
PS. I'm on IE11 now and it is absolute crap. Response is terrible here, icons and some advertising not showing up. buttons missing. wow. craptastic.
