Of course they do, and that work continued while other people worked on the rebranding. Also, and more importantly, maintaining an up-to-date brand keeps Mozilla relevant and (hopefully) stops them looking like a throwback to a past era (like, say, Yahoo!). Mozilla needs to do many things to remain an important force on the web. Keeping it's brand is one aspect of that work.

They are very aware it seems based on my observations over the last few years and while I don't agree with everything they do I defend their right to spend a tiny fraction of their time on a logo.

- after all it seems logo, ui and pixel polish etc matters a whole lot more to a lot of people than it does to me so it might be well worth updating.

Me? As long as extensions work and they don't copy too much more (bad imo) ideas like hidden menus and hamburger from Chrome and Mac they are still easily my favourite.

Oh, and they have created a new systems programming language that has managed to exite me and a lot of others here on the northeastern side of the Internet.

People keep talking about Mozilla like it's the engineering wing of the EFF, that it's tirelessly working on a mission of Internet freedom, etc.

I'm sorry, but I just don't see it. I see:

(1) a team of developers, incrementally maintaining a codebase that that was donated by a 1990's commercial entity, and

(2) some second-tier marketing types, burning through Google/Yahoo money and padding their resumes with random "me too" projects that don't last very long.

The flagship browser has only had one major re-think since Netscape's demise, and that re-think was, "We should make its UI and dev cycle look like Chrome's". The most significant "new" project dreamed up by the marketing types was a me-too Android alternative, which they then almost immediately canceled.

The only noteworthy and truly innovative things I can think of coming out of Mozilla have been Rust and Persona, and the latter was also quickly canceled (which was a shame since it's the only example I can think of that REALLY fits the mission statement they talk about).

I'm glad that Firefox is out there to prevent a Google monopoly, and I'm glad that Rust has a financial patron since it's a pretty interesting language. But if Mozilla want to be seen as some greater "force for Internet freedom", beyond just maintaining an dated and declining web browser, then a logo change won't be enough. Actually DO some other stuff without canceling it.
