Headers are messed up, technological help?

[Jack]

So I've gone to facebook and tumblr this morning and both of their headers and page layout are messed up. It doesn't seem to be happening to anyone else but me. I restarted my computer. I was wondering is anyone could help me with this?
Here is what the facebook page looks like:

Here is what it looks like when I try to look at notifications:

And here is what my tumblr looks like:

Please help I can't do anything with them like this

If all fails, get malwarebytes (google it) and run a scan.
