Facebook not working in Internet Explorer

Like the title says...
I can't connect to Facebook on IE anymore. Almost* every other site works too, and Facebook works just perfectly in Firefox.

I've already reset my router because that was the solution for a similar problem months ago, but it didn't help.
Cookies and everything have been deleted too.

I'm using IE 11. On my laptop I have IE 11 as well, and there it works just fine.

Does anyone have an idea why this is happening???


* I also can't connect to my bank's online banking page either. Could it be that some high-security sites aren't working or something? Do they have something in common?
