The Firefox HELP tab keeps appearing every time I open the app or a new window. Firefox 3.6.28, Mac OS 10.4.11

I do not understand what you mean with the "Firefox HELP tab" If a tab opens with a specific page when you start Firefox then you need to check the Home page setting to make sure that that page isn't set as the home page. See these articles for some suggestions: *https://support.mozilla.org/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox *https://support.mozilla.org/kb/How+to+set+the+home+page - Firefox supports multiple home pages separated by '|' symbols If you do not keep changes after a restart then see: *http://kb.mozillazine.org/Preferences_not_saved

You're welcome
