I was referring partly to Mozilla's responses to the reaction from corporate support people over their forced-updates announcements. But, they've also had display bugs around for almost 10 years [1], and they've banned bug submitters over etiquette issues without actually addressing the bug in question [2].
And now for the part that will probably make me really unpopular here: if they fix major issues in an upcoming update, that's great. But, people have been complaining for years about performance problems, and IMO there should have been a show-stopping effort to fix it a long time ago, rather than the incremental efforts that, to many users' perceptions, have made little to no improvement.
The push towards rapid release cycles in many parts of the software industry seems to be leaving behind the principle of getting it right the first time.
Anyway, that's all the time I have for this nonsense, because I've got a couple of projects of my own with unresolved issues, and I don't want to be a hypocrite.
