The main problem with Firefox is Gecko.

Technically it's a great rendering engine, fast, standards-compliant, maybe only slightly more buggy than Webkit. Unfortunately it has a different set of bugs than webkit. Web developers have just so much time to debug the apps. Once the app works for ~90% of users on webkit, spending as much time or more testing and debugging for ~7% of FF users is not always justified.

This is a catch 22: FF users get more bugs - more pressure to move to Chrome, fewer users on FF - less money to develop Gecko leading to more bugs. My prediction is that FF will either drop Gecko or die.
