There is a new extension in the works for Firefox called Ubiquity. It brings natural language command line interaction to any webpage. Its pretty groundbreaking. Below is the video from vimeo. Its really worth watching.
Last night I installed the latest version of Opera (9.63) in response to a bug report. I have to say, I’m pretty impressed with this version. The problems I’d noticed with previous versions (primarily it being slow as Christmas) are gone. Firefox now has something to be concerned about in my opinion.
