Forest and trees… who cares that you made it faster if continually less and less people use it. The extreme majority do not care about tiny improvements to speed.
If they were interested in growing market, they would be integrating ublockOrigin and other anti-ad software. They literally have nothing to lose anymore.
But, it’s okay for Firefox to own 2-3% market share?
Then add on stupid things, so all their users, each release, have to fight to turn off dumbassery, and restore functionality.
They've literally done everything they could to destroy market share.
For example, firefox users of all sorts customized things. People loved it. Themes, plug-ins, add-ons.
Firefox devs consistently fail to realize that "configurability" is a category, not "this tiny configurable thing".
So they've removed configurable after configurable option, each option only having .1% market share usage or what not, not considering that overall... they've now alienated 20% of their user base.
Telemetry shows them a tiny percentage for each feature, but it is the collective feature set which matters.
And that has a cumulative effect. 20% upset users, all saying "Don't use firefox!", doesn't help.
Then they add useless, in your face, obtrusive and annoying features, and people scramble to diaable them.
"Oh so sorry, disable that?!". Sometimes years go by, and all the instantly closed bug reports add up, and they finally relent, fix it. Of course, everyone who cared is now gone, and will never come back, and now campaigns against firefox.
Just like the infamous tab detach issue, which took half a decade to resolve, by finally adding an about:config option to turn that off.
And who cares for telemetry, when hundreds of users complain, and bugs are ignored, or just hostile closed?
Mozilla is broken. Firefox is on the wrong path.
It is sad.
