Firefox become popular originally because it differentiated itself from other browsers (well, mainly one particular browser) by offering great useful features that the others didn't have. Many of them were targeted at power users who went on to evangelise Firefox to others.

These days Mozilla only seems to get publicity and attention for gimmicks, or for removing features. The few useful ideas it has produced, like Containers, languish in obscurity. In the face of Google's aggressive moves with Chrome, Firefox has withered has a result.

A change of direction is sorely needed.
