I don't know what is this for but when I click on this add-on pinned icon, nothing happens.

A very useful add-on. Thank you very much.

Great time saver!

an experience beyond description...

Installing this makes my experience on the web very pleasing, now having to worry about things I have to agree anyway. New functionality is to "allow only required cookies for the site to work properly" and that's great. Great addon!

It's very practical to allow cookies with a single click, esp. when one does this quite often. However, it should also provide for settling third party cookies option -- 'Always', 'Until expires', 'Never' -- if not everytime, at least in the Add-ons section. I am sure this would be quite easy.
