As this will - God knows how - make Firefox believe every page's HTML is a single <div> (that's right, no <html>, no <body>) it has the ability to break absolutely everything. And it will: from basic right-click menu functions to every other add-on out there.
Yes it provides what it promises, but apart from that it's the worst extension I ever came across - if you can't find an alternative disable it after use! You've been warned.
