Although they seem a contradiction my argument is that they took on a development life cycle that was far above their means.
I would have loved Firefox to come out on top as for me they changed the web when they introduced tabs but they have been slow on innovation since. I feel Chrome gave them a kick and they responded, companies shouldn't operate like that, innovation should continue regardless.
I say I wouldn't care to look because I have moved on, Chrome goes above and beyond what I want from a browser, speed and stability. If Chrome starts to go in the direction of how Firefox went I would have no issue in trying another browser. I don't have time for allegiance to a browser, I just need it to work.
"They may have redeemed themselves recently but I wouldn't care to look"
These two sentences feel contradictory to me. If you want Firefox to win, at least give it a try once every few versions.
