This is what happens when humans achieve success. Rather than maintain the course they are obligated to exploit to the nth in order to squeeze every gram of return from an idea(product) until they can get no more. Then, they will get creative and pull out every hook & crook to squeeze some more. Thanks Mozilla, for everything up until your mass-collection, feature- bloat, entrapment blitz you've set out upon. Perhaps DTA will make their plug-in compatible with PaleMtoon now. Chances are the forks will come out on top & Moz can go f-up Thunderbird & Seamonkey for awhil as their top-heavy pyramid topples.
edit:admittedly a pipe dream, markets ruled by duops and oligops never lose the top players, they just cannibalize each othet and bloat.
