Got upgraded last night. The layout seems cleaner and it's probably faster, but it's frustrating that most of the popular extensions work because they haven't upgraded to the new api. The biggest problem for the time being is that I cannot save my session before I close the browser. Any suggestions? From what I understand, firefox was facing a precipitous decline the past few years. Hopefully this update revives it. But what kept me using it besides habit was the extensions and ability to customize the interface. If they don't fix this soon, this might prove the death knell for them.
