I'm confused. I get a new Firefox version on my Windows, Android, and Linux machines consistently, with new features, fixes, and the latest web tech minus the privacy nightmares Google is trying to feed, at a regular basis. How are they not investing in FF?
The person you replied to did not say that Mozilla is _not_ investing in Firefox. I too am worried that Mozilla was cutting Servo development, in a time where Firefox already has a problem keeping up with new web features.
