This is a great add-on! I've been using it for years and it's a lifesaver!

If you install the extension after having used the browser previously, the currently saved cookies will be saved as permanent for that site. But you can go through the Manager and delete those that are not needed or set them as temporary.

This is an amazing add-on that I highly recommend, it does everything I need and hopefully it keeps working fine like this for many more years.

As a replacement for Cookie Monster, CookiErazor does as much as it can under the stricter rules of Firefox 57 ("Quantum"). One big difference for Cookie Monster users is that the default Firefox preference has to be set to allow all cookies. Then CookiErazor preferences are set to erase cookies when the tab closes or Firefox quits. (In other words, you can no longer have the default set to refuse all cookies and make exceptions via Cookie Monster, so if you want to keep cookies for some sites you have to accept them for all.) And of course, for a specific site you can set it to keep the cookies. The icons could be better, like the optional set in later versions of Cookie Monster: eg, a red circle if the Firefox default is to refuse cookies, a yellow circle if CookiErazor is set to erase after closing tab or program, a green circle if CookiErazor is set to keep the site's cookies.
