I get and agree with focusing resources where you get the most payoff. But there is also something to be said for product differentiation. These two features definitely differentiate Firefox from Chrome and Safari, and do so in a useful way. There have been times that Tab Groups was the sole reason I stuck with Firefox. There have been times that the sole reason I did not move to Chrome was knowing I could never 100% personalize the GUI. Throw in the how Mozilla handled the DRM issue as well as Pocket and new tab sponsored websites fiasco and you begin to erode the privacy reasons for sticking with Firefox. Yes, Firefox must compete, must stay competitive, but if it becomes just another Chrome, there is no way they can compete with the resources Google can bring to the table. Firefox must compete on product differentiation or it will lose.
