I updated to the latest version of Mozilla Firefox, which came with some add-on called InfoAtoms, some program to stop Adblock Plus and was displaying links like "About This Ad" all over my YouTube profile and similar things on KH-V and other sites (I didn't click them, though). I disabled it, but how can I remove it? I see no "Remove" button. Edit - 9:31 AM PDT: It doesn't look dangerous, but it does have a lock to prevent you from removing it, which I want to do. http://www.shouldiremoveit.com/InfoAtoms-7879-program.aspx Edit - 9:34 AM PDT: Looks like it's been on there since December 20, 2012. I wonder why it was just enabled? Anyway, I uninstalled it thanks to instructions in that link. This can be locked.
