The ship has long sailed after they killed their addon ecosystem by killing XUL addons. The quality and feature-sets of addons took as much a nosedive as their user-share.
Since then, they were keen on continuing this trajectory, and introduced multiple UX/UI regressions that alienated all (most?) of their power users, sometimes even disallowing fixes through about:config.
That .gov analytics site that was posted here yesterday showed Firefox setting at 2.4%, which is just about right for all the string of horrible decisions they've made.
The horse is dead, Jim. And, unlike an old movie or a videogame, almost no one is going to have nostalgia feelings for a web browser.
I have more nostalgia for old Firefox [EDIT:] and for the old W95/NT4/98/2K GUI [/EDIT] than for any game or movie.
Yes I know there is talk about privacy and security issues with telemetry, and I don't necessarily like it myself, but if we don't vote with our data then the developers of these systems won't recognise what we use and we will lose it.
Probably not the most popular view around here but if companies use these metrics to decide what is important then maybe we should contribute some data.
Got I hate telemetry. I usually (and I imagine many people) turn it off because I don't like my stuff phoning back to the mothership, but then some brainless moron mindlessly uses their "data" for decision-making, and rips out good features.
This is especially dumb for Mozilla. Who do they think still uses Firefox? The people who want some dumbed down minimalist lookalike? Their overall browser market-share isn't too much more than Samsung Internet, and probably the only reason anyone still uses it anymore is that it's not as dumbed down as Chrome. Maybe they should just run with being the browser for power users, with all kinds of interesting niche features and customization.
Honestly, UX telemetery probably should be banned for everything except error reporting. Nothing good seems to come of it. If you want to know what people do with your stuff, just try to empathize and maybe have some focus groups.
