>> I want to make it as easy as possible for users to try out and adopt. Just testing it out? No installation required. Why not offer an option to try it out in the browser(with same GUI), and if they want security tell them to install it(and verify)? It would be just a bit harder than installing the extension. BTW:there's another use case for extension based encryption: As the backbone for private messaging for various sites(which requires integration with the browser) , for example reddit. private messages in reddit are : (a)viewable to sniffers due to http usage (b)can be viewed by reddit staff (c)can be viewed by dragnet and targeted surveillance An extension would definetly reduce attack scenarios, and has a good viral marketing vector. In fact implement the right way i could see it being a very reliable way to making something like this popular.
