If certain rulesets are activated all rulesets are set to default
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.
