Unfortunately, I was looking for something that will save cookies in the Netscape format - this one doesn't. Or maybe it think it does (I saw mention of Netscape in the change log), but other tools such as youtube-dl do not recognize the cookies.txt file saved by this extension.

I've recently learned that this cookie manager does not import cookies correctly. I was messing around with Evilginx and I could not get it to work. I then tried Cookie-Editor (by cgagnier) and I was able to get it work as shown in the YouTube videos. I could not figure out how to import cookies into a specific container. Also, even in incognito, it still shows all cookies so not sure where my imported cookies wound up.
