How to remove indeed.com malware?

So first of all, im not sure if this is the right exchange.
Also, you can't find anything on google for this which is really aoying.

So since a few days I have some adware on my browser (you know, just like extra toolbars or a starting page).
I get this sidebar from indeed.com on multiple websites (stackoverflow too for example):

I also get random popups and link overwrites from it. The problem is I have nothing on my pc which would indicate software from indeed.com, I already ran anti malware bytes twice and I have nothing in my FF plugins/addons either.

Thanks for help in advance!
