I find that I agree and disagree on a few points. I do wish they'd kept their focus on the technical over the marketing. I don't think they really needed the swaths of MBA types in charge of the organization, and wish they'd stayed closer to their technical roots which is what survived from the earlier Netscape through AOL and into Mozilla. I was also an early fan from Phoenix, though I think the Firebird name (also a fan at that time of Firebird SQL) was a misstep.

I think some of the more encompasing efforts haven't all been bad. Rust as a language has been a great thing to come from Moz. Firefox OS could have been interesting as well.

For that matter I'd have been happy to see broader adoption of Mozilla's identity efforts, and don't so much mind them trying to get VPN as a secondary funding source.

I do wish their structure was more geared towards keeping the technical and developer teams as a focus of the organization over the more commercial aspirations.

I will say I did switch to Chrome around 2010 mostly because I really do prefer it's UI/UX ... FF is getting closer to that, despite some really not liking it and I've considered switching back.

I also find it ironic how popular electron has become, when XULRunner was such a great platform well over a decade before. I do think there's opportunity to create the next npm in concert with deno and firefox for supporting a greater module approach. There's still some unanswered bits there. Similarly, still would like a way to do bundled application packages; similar to jar or silverlight that's just a zip file of assets with a manifest and modules.

If often feels like Mozilla is doing their own thing to try and gain market share instead of working with the broader community.
