Greasemonkey-like mods, but quicker to tweak. Create and apply your own synced tweaks to web pages
So you want to make a few tweaks to your favourite web page, but don't want to build a full-blown extension? That's what Control Freak is for.
Adjust CSS for just the web page you're viewing, from the comfort of a toolbar button. Or make your CSS work across the whole domain. Or on every page.
You can also see open a Management view to see all your Control Freak tweaks on the same page.
Extension is intended to be a simple replacement to Greasemonkey.
