This might be an unpopular opinion here. I support the work of Mozilla wholeheartedly (I've even thought about applying to work there). But Firefox is miles behind Chrome. It has a few features that Chrome doesn't, but I find developing on it a pain, and it's incredibly annoying when common sites (reddit / imgur / many others) don't perform well (which is more Google's fault than Mozilla - devs aren't supporting Firefox like they do Chrome). There are so many small features that don't work well on Firefox or can only be fully utilized via shady extensions (pinch to zoom, multiple accounts).

As I write this post, the browser has frozen twice -- this is a new development, will try and sort it out.

I don't want to go back to Chrome, and so far I'm holding out, but I think that it just works better than Firefox right now, and it's really frustrating to feel like I don't have a choice if I want to protect my data.
