For me Fennec's biggest shortcoming has been Flash. I'll see if I'll have interest to install this.

The second shortcoming is it pulling up mobile sites instead of full ones. Why should I be interested in going back to mobile sites when MicroB's attraction has all along been full site access (and ability to handle them)?

Also, it just seems that everything from startup to loading pages is a little slower on Fennec.

So there's really not much else going for it, except proper graphical settings page, tabs and the eye candy.
