Just because anyone "can" contribute doesn't mean every patch is accepted or that product decisions are delegated to corporations with competing products. Firefox still bears responsibility for its own product decisions, not to mention how firefox is marketed.
absolutely correct, but Firefox takes notice of ideas.
They can be influenced by what is proposed as fixes or contributions.
"Everyone knows" that Firefox may break some websites, just ask google.
Has anyone ever come across that pretty regularly?
Firefox has become a follower rather than a leader and I think the influence of contributors has done that.
It is no good for Firefox going in a direction that a good deal of their contributors wont go. The users be damned!
