There is something to be said about that. Firefox does keep inserting it's 'helpful features' like Pocket on users, which is very annoying.
My point is just that everyone is so critical of Firefox, when the alternative is disproportionately, orders of magnitude worse for the user.
I'd rather bash on minor Firefox grievances when it's the #1 browser, not when it's losing/lost the browser war and it's our last chance at browser engine diversity.
