What is Forget Me Not?
Make the browser forget website data (like cookies, local storage, etc.), except for the data you want to keep by adding domains to a whitelist, graylist, blacklist, or redlist.
Features: This web-extension deletes data websites store in the browser in the following situations:
When all instances of a website have been left:
-- Cookies -- Local-Storage (Firefox 58+ only). -- History & Downloads. -- Different cleanup types can: 1 - Never: No cleaning. 2 - On Startup: Clean only on browser start. 3 - On Leave: Clean on domain leave and on browser start. 4 - Instantly: Prevent data from being set, if possible. Otherwise behave like On Leave.
When the browser starts:
- Cookies (optionally only when not whitelisted).
- Local Storage (optionally only when not whitelisted on Firefox 58+).
- History
- Downloads
- Form Data
- Passwords
- Indexed DB
- Plugin Data

Delete thirdparty cookies on creation:
- When a cookie is set without belonging to a domain that is open in a tab, it is considered a thirdparty cookie.
Manually clean the above.
