I know you must get many common questions like mine, but I really don't have a clue.

Ok, I um... recently tried to install adblock (originally chromium-based) that now is available for Firefox users, but is not supported for Pale Moon yet. Yeah, I get that message saying "Not available for Firefox 24.7." So my real question is, when I run into these problems, who do I contact to help me out with this issue??? Is it MC or the developer of the add-on that I contact? So, without knowing yet and waiting for a reply, I'll go ahead and message the adblock team/devs to get a hold of this situation a little better.
