It works great, even with the Multi-Account Container Add-on.
With this Add-on, I can remain signed-in for certain container, while removing all other cookies and data I get spammed with.

Love this extension, great for personal and work use cases. For the love of god, can we have it on android already!

Danke das es euch gibt

It seems to work perfectly. Add all cookies you want to keep to the white list and then activate automatic cleaning.

A nice and customizable way to take care of cleaning cookies, cache, etc. The wiki/github page helped me fix an issue I was having; it is very well written and organized.

My one suggestion is to make a setting so it doesn't clean add-ons, but you can solve this by moz-extension* to stop it from cleaning them. You can also just disable one by doing the full url.

Excellent.
