Primarily for those who have Firefox set to “Never Remember History” Or those who clear all their cookies. This concept will retain settings cookies for DuckDuckGo by keep them isolated so that only DuckDuckGo’s webpages can read and edit DuckDuckGo’s settings cookies. This will eliminate the problem of no intuitive design and use when browser settings secure data by remembering history and data only for current browser sessions.
Preferably add to all versions of Firefox at the same time.
