See https://support.mozilla.com/en-US/kb/How%20to%20set%20the%20home%20page#os=win&browser=fx8. Is the welcome/start-up page listed as one of your home pages?

what i need to get rid of it "the tour". that's what keeps opening when i open firefox after it's been closed but kept in my dock. thanks!

1) What is your home page setting?

2) Attach a screenshot of what you are referring to. Not familiar with any tour feature.

http://www.mozilla.org/en-US/firefox/central/ above is the page that opens.....i have "mozilla firefox home page" as my home page but the one above opens first. maybe this will go away in a few weeks. i just updated my firefox...
