I appreciate that Mozilla is undertaking initiatives like this. I really do.
But in the most important ways, they have become hostile to their users by destroying their add-on community and making many developers flee in disgust.
Without the add-ons that allow greater control of the browser, there is just no long-term reason to use Firefox compelling enough to matter.
Itโs sad, but itโs true. Making the browser a little faster wonโt change a now years-long history of terrible decisions and user hostility.
