How do I get rid of this weird bing page when I open a tab on firefox?

I don't really feel like typing.

It keeps doing that even though I have set the new tab homepage to google.

Please help.
Also when I open a new tab it goes unresponsive when I try a search, making it extremely annoying.

Remove it from extensions.

Nevermind, it was the Speedfox add-on.
