France wants your browser to censor the web, and Mozilla is petitioning against it

No, it's not. It's just not. The important question is how the law is written. Wild guess: they won't target "browsers". They'll target "means to display remote content" or some shit to not have people rename browsers to surfers to evade that law. And depending on how generic they'll make it sound, it'll be a pain for not only every piece of software but maybe also stuff like digital binoculars or phone sex companies or whatever.
