works perfectly but the setting is gone occassionally for no reason so I have to customize my setting over and over again it really annoying what should I do?
I'm sorry, it will take some time to investigate. If settings for other add-ons are gone too, it may be that Firefox profile data is broken. This my be not problem of this add-on. Anyway, I will add buttons to import/export setting on version 2.15
If there is an error log at the bottom of the setting page on version 2.15.1, please report it.
