Thanks for taking the time to write a review. I just checked your link and it works for me. Several things might be an issue here: 1. You need to actually enable cleanup in the settings in addition to creating rules, since the cleanups are disabled by default. 2. On Firefox for Android, the local storage cleanup is not supported. 3. You might have your rules set up to prevent cleanup on that domain.
