Not a complete solution Rated 2 out of 5 stars
While this tool does seem to do a better job that the built in cookie tool that ships with Firefox, there is one glaring omission that users of this tool need to be made aware of.
It states that "cookies belonging to the current page" will be shown. This is only true in part. The massive oversite is that it does NOT show any 3rd party cookies, which arguably are more important when building a tool to do a cookie audit of a site.
Granted that the developer could argue that these cookies are placed there by a 3rd party and don't belong to the current page, but the truth is that the current page has allowed these cookies to be placed and is therefore liable for them, so in my mind, would come under the umbrella of "belonging to the current page".
Shame really, as this one comes close.
The omission of being able to launch from the add-on bar is another bugbear, especially when there is no facility to refresh the list or watch what's being added like you can in the Firefox provided one. 3 clicks gets very tedious, very quickly when repeating it a lot.
