Firefox is bleeding market share and has been for a while. Despite this, revenue and profit is at an all time high for mozilla which is weird as the revenue comes from sending theirs users to google for being profiled and exposed to ads. Meanwhile long time users lose faith and trust in mozilla and firefox.
Not exactly the best time to be caught having "a little fun" move showing that they will sneakily install stuff in your browser without asking.
Then again mozilla is "making far-reaching and very short-sighted decisions in a vacuum."[1]
