This is a great extension for anyone who's looking for a little more control over their cookies than the default Firefox options (which offer very little in terms of granularity). Developer is very responsive here as well as on Github (Which I must remind everyone, is where you should direct all issues, bugs, etc.). There are a lot of people who've written reviews here that obviously lack the technical understanding to effectively use the extension, let alone accurately rate and review it. This has unfortunately led to some poor ratings and reviews that aren't actually warranted. I went through the first 10 pages and with the exception of 3-4, just about every poor rating was someone who either didn't understand that cookies hold session and login status info and are upset that deleting the cookies signed them out of all of their accounts (an expected result if you don't set up the whitelist), or otherwise had a poor expeerience completely due to their lack of technical understanding.

I felt the need to write this because it really is a great app with a developer who's actively listening to community feedback. They deserve to have someone call out these sorts of misunderstandings which have led to inaccurate reviews. Anyway, I recommend it!
