The Brendan Eich controversy and the new Chrome UI ripoff for Firefox really isn't doing Mozilla any favors with their fanboybase these days. Users are becoming sick of applying bandages to their browser to make it work and look the way they want it to, and the CEO mess really sealed Mozilla's fate.
I'm glad to see the wretched browser known as Firefox going down the tubes, but sad that so much potential at Mozilla was wasted on copying other browser's UIs and making a garbage mobile OS based on their elderly browser engine instead of actually innovating.
Hopefully, if Mozilla ever recovers their community's trust and actually makes a decent browser again, they will become great again. But right now, it's a big nope.
