They are losing market share and their actions will accelerate, not reverse, that trend, just as previous missteps have done.
Ah yes... previous missteps.

The last straw, the item that chased me off FireFox was the developers' stupid decision to lock down the reload and stop buttons on the FireFox UI. Yes, I know there is a "Classic" add-on that attempts to restore the previous look and feel of the UI. But like many add-ons, the quality level of that add-on is much lower than that of FireFox. I ran into too many issues trying to get that add-on to work properly. During my attempts, various items in the UI would actually disappear, and I would have to restore the browser's profile directory and try again to configure the Classic add-on.
Yes, FireFox developers are chasing away their users.. Now I just need to figure out what to do with my "Take Back The Web" FireFox t-shirt. Ironically, it looks to be time to take back the web from FireFox.
