Ultimately, advertising is a form of inefficiency both for the end-users and producers. Perfect world, user's are aware of products and services they do/could/would want without annoying grabs for their attention while producer's can either reduce prices or focus capital elsewhere. Finding models that successfully reduce advertising inefficiencies is better for everyone. Consider how much better the internet is than television and print newspapers/magazines where you actually pay to consume what contains a substantial amount of advertisement (over 1/4 for television).
Because advertisement is a necessary efficiency I don't think just blocking advertisements is really a solution. For now, some model of efficient advertisement is better than the growing number of bloated and data gathering websites out there. I don't see any of the other browser vendors making efforts to move this forward.
Yes, a new browser is annoying and then again perhaps we wouldn't need one if Mozilla hadn't fired Eich for his political contributions?
