Absolutely love it! Just a few tips:
1. To make sure that you're kept signed in on sites that you want, make sure to click the cookie icon in the upper right and "+ Whitelist" the options that have an asterisk (*) right before them.

2. Make sure that you're periodically exporting your "Core Settings" and "Expressions" files to a cloud service, such as Google Drive or preferably a privacy-respecting provider (freefilesync.org, sync.com or Proton Drive). Then, if you ever want to apply your extension and website cookie settings to a new browser or machine, you can just use the Import function from the files from tip #2 and seamlessly pick up where you left off.

Cookie AutoDelete is recommended by PrivacyTools.io and for good reason. If you haven't checked them out already, they have fantastic online privacy and security recommendations!
