Sorry if I'm doing things the wrong way. First time ever filing a bug. If all rulesets are activated in development8 of the firefox version the add-on resets to standard ruleset settings. After experimenting with activating as many as possible I have been able to narrow it down to only; StudiVZ (disabled) Tcodevelopment.com YouMail (buggy) Resetting all rulesets if activated (and browser restart) ------------- However if one resets all rulesets to default first, and then activates those three (in addition to the original/default rulesets) all is fine and they are not disabled. So the relation between rulesets seem much more advanced than my understanding. ------------- I have never added any of my own rulesets, all are the ones that have been included in HTTPS everywhere as standard.
