Doesn't perform its primary task efficiently anymore, simply deleting cookies! Becomes too complicated and doesn't delete even after several requests! I don't trust this application anymore!
If you are using strict mode, it is a known bug. On GitHub, I explained that the bug is due to the new cross-site cookie isolation introduced in 86. This is enabled if you use strict mode or set it in custom. This is a bug in Firefox Webextension API itself and it is out of our control.
