nice start, hopefully will improve Rated 3 out of 5 stars
this is looking pretty good so far, but i think it could be easier to operate.
i think the word "exception" is unnecessary in the menu items - seems easier to me to just have "allow", "block", etc.
seems simpler to add "allow" and "allow session" directly to the menu rather than open an unneeded dialog.
Cookie Monster is easy and offers better, more granular control - my only gripe with it is that the he has failed to add a toolbar icon thus far. i would suggest the dev for CookieFast check out CM if he/she hasn't already.
i'll be keeping an eye on this though.
