I'm guessing you're talking about the extension manager of Firefox which displays recommended extensions. If I'm not wrong and that is what you're talking about, then you can simply disable the display of recommended extensions. Open a new tab, type '''about:config''' and paste this string in the search box: '''extensions.htmlaboutaddons.recommendations.enabled'''. Set it to '''false''' and restart the browser. If you're asking about something else, I'd suggest for you to show us a screenshot because the way you've written your question it's very... vague. <i>'''WARNING: Changing preferences through this interface not officially supported''' Hidden settings edited using the about:config tool are explicitly not supported, which means that Mozilla makes no guarantees they will be supported in the future, or that Mozilla will fix them if they break. Mozilla does not test these preferences, and will not in the future. That includes security and performance testing which these preferences may affect. </i> ''[Warning added by moderator.]''
