Great. Coming just in time when people think the "main stream" browsers are too boring.

I'm actually glad to see Mozilla has grown a little bit "predatorial" if it can bring good to the users. The implementation is polite too, as it lets you know there was an ad been muted.

There's a lot of things that can still be done in the browser space. For example, one-click login even without entering email, easy purchase without the website ever collecting your card number (or other financial detail beyond necessary), etc etc. Ads can also be improved too, by making them not violating nor annoying.

The possibilities are still great, I hope Mozilla can figure out a way to tap into it.
