I know they screwed up recently with the Mr. Robot malware, but I think it's really important for developers to get behind Firefox again. As the American government fails to provide any sort of check on its behemoth corporations (Apple, Google, and Microsoft) and to protect consumer privacy, Firefox is basically the last contender for real consumer protection standing.
I’ve found a lot of people are quite naively idealistic around browser development. The rendering, JS engines in Firefox and Chrome are state-of-the-art and take small armies to build and maintain. Mozilla has to strike a balance between revenue seeking and consumer protection seeking behavior that I would imagine is quite difficult to maintain. Lots of people here additionally are up in arms their incredibly specifi…
Maybe their incredibly specific workflow involves a piece of multi-million dollar equipment and updating to a new API involves reflashing its firmware for some crazy reason. (alternately, 100 $200 pieces of equipment in hard-to-reach places that must be manually reflashed.)
2 years may be roughly the maximum attention span of a software project, but 5 years seems like a better number for bedrock systems like web browser.
I don't mean to trivialize what goes into Firefox, just that backwards compatibility is a big deal and most software companies don't take it seriously enough.
