- A new Firefox extension that lets people customize their experience of the sites they visit is stirring excitement among Web surfers and consternation among security experts. That capability has gained the extension an avid following of Web surfers who want to customize the sites they visit, removing design glitches and stripping sites of ads. But the extension comes with substantial security risks, and could stir trouble among site owners who object to individual, custom redesigns of their pages.


Very nice indeed
