Hi Ce Add-ons for Firefox for Android are developed and supported by a community of independent developers. The page that you downloaded the add-on from will have a Support link for you to get help with this issue. Before you do however, you may wish to look at the bottom of the Firefox for Android menu (the three dot icon) or go further and select Add-ons and the add-on in question to see the settings that are available. I hope this helps.
