Decent add-on, I think it's the only one that lets you do this sort of thing - editing cookies.

At first I thought this add-on didn't work because I tried to change the "Path" attribute and the changes wouldn't save. (If that's what you're trying to do, write down the current cookie values, delete the cookie, then add it with the new Path value you want.)
