 ## Warning regarding stability
 
 At the point of writing (2024-07-29) the maintainer considers the add-on to be in an experimental state. Although all basic functionality is implemented and manually tested it still needs more  real-world usage to call it stable. It should also be noted that - although the code was carefully written - the developer had no prior experience in developing add-ons for Firefox or Thunderbird and implementation might be faulty due to this.
