The feedback of "Android version of Firefox is unusably crashy on my phone" is not something any developer can take action on. There are no example sites, no steps to recreate. I agree it should be in the bug tracker, but adding anecdotes without specifics does not add much to the conversation nor does it help to move FF forward. Are we arguing all users of this specific device experience the same issues as this user? If not, not even the device model is helpful. As I pointed out, I was not trying to stifle feedback but to point out that for every "FF is too slow" complaint there are just as many "works fine for me comments" that are equally useless. How is FF slow, in what use cases, how cane we recreate these problems? That is worthy of a bug report and if that information is available submit it to FF to make the software better rather than complaining on a thread about Chrome removing a useful extension that FF supports fully across platforms.

All points I generally agree on, except that this isn't a discussion with Mozilla about improving Firefox. This is a discussion about Chrome that diverged into a discussion about Firefox in a very general manner. You may not be stifling feedback, but you're riding on the assumption that feedback is the purpose of the discussion going on, which it is not.

You keep bringing up this point about feedback that is irrelevant to the actual conversation at hand. Nitpicking feedback is kind of useless and pedantic when the purpose isn't to be feedback.
