Just seeing the comments here exasperates me...
So for those who don't know, the Internet is heavily biased towards Chrome. Simple pages that should render no differently in FF than Chrome are often broken. This "Chrome is great, screw everything else" attitude is exactly how we ended up with IE and stagnation in standards/development in the late 90s/early 2000s. The biggest feature of IE was faster rendering and better performance versus Netscape.
It's seriously an issue that developers/engineers are only targeting Chrome and I think a large part of that is also due to V8 powering Node.js. I'm not trying to bash Node here... Developers are so hooked in its (chrome) ecosystem they don't even realize the bias. I'm beyond excited to see things like Chakra being able to replace V8 in node because I think it will be a huge boon to making a more free and open web.
Anymore I've started to protest by refusing to use sites that are flagrantly broken in FF. I block em in /etc/host and call it a day. What happened to standards? Why can't I use a browser you don't like?
Also FF for those that haven't used it in a while:
•) it uses less ram than chrome especially with a lot of tabs open
•) is quite performant and getting better
•) has vastly improved its Dev tools... the folks responsible for them are very receptive to ideas and happy to hear them.
•) multi-process Firefox is MUCH more responsive than its single process alternative but must be enabled currently (I think). Also make sure your extensions are compatible with it.
•) personally, I think, the developer edition Firefox I think is much more attractive than Chrome
I really hope the web doesn't just work in one browser and that things start to improve. Reading comments here gives me little assurance that will happen :(
Edit 1: formatting and note about folks making the FF Dev tools.
Edit 2: clarity in final paragraph and added sad face.
