Firefox 4: Stop tabs from appearing as separate Win7 Aero peek previews

I like the Aero peek previews, but when programs abuse them it becomes really difficult to see what you're doing.

Oh the horror!

Now you're probably thinking... what's the big deal, right? Well each browser window will add more previews, and with my insane super-nerd 5x browser with 20x tabs in each browsing habits, that'll equate to a lot of previews.

Click on the Firefox button in the top left corner and select "Options".

Select "Show tab previews in the Windows taskbar".

That's it, you're done!

Now you're normal again.
