Back when I did web programming all the time, I had a really good experience reporting a bug to Firefox (where they were incorrectly throwing an exception for something the DOM spec said should be a no-op-- they sent me a t-shirt.) Around the same time, Chromium added a regression where trying to search for text on a long page would fail to work (I can't remember the details, but it was about of equal severity to the Firefox bug.) My bug to them was completely ignored. (It ended up fixed in the next release, but I don't know how-- my bug was never triaged AFAICT and there weren't any dupes AFAICT. Maybe they had a second, private, bug tracker?) God knows I've disagreed with a lot of Firefox's design decisions recently, but they really did a good job of engaging with their users. At least back in the 4.x timeframe.
