It works well enough for now. I'm uninterested in further updates until I decide that further functionality or specific issues need to be addressed.
I use three different computers throughout the day, and I've been getting plagued with these "Firefox has updated and needs to restart!" about a dozen times in the last couple of weeks .. and I am quite tired of it.
Constantly rolling out microfixes as a default is STUPID. Save up the changes and release them as a major version improvement. I already left one company that didn't seem to want to adopt this strategy and look where it's got them.
