I use Firefox and whenever I startup an extra tab opens as well as my homepage. I delete this tab but the next time I start Firefox it starts again. How can I get rid of it.

Look under Tools\Options\Tabs on the main toolbar.
You can control the browser's use of tabs there.

Thanks dlwolff0 for your suggestion. Tried it earlier but no luck. The rogue tab still pops up everytime I open Firefox.

Have you tried this?   Clear all tabs that you don't want, setting (and arranging--the left-most one is what will display when FF first opens) those that you do, and at Tools/Options/General/ click the Use Current Pages button.  This should make the tabs appear the way that you prefer when opening Firefox.  

BTW, I have a number of startup tabs, not just a homepage, and one is a blank tab so that I can open a website that I type into the destination window without overwriting the currently open tabs.  I know I can open a blank tab with Control/T, but I do this so frequerntly it is a saving in time.

Thanks gorf for your suggestion. Did what you said and solved the problem. Didn't think to check thr current page option earlier. Have also added a blank tab like you. Thanks again. Sometimes the solution is staring you in the face but it takes someone else to set you straight.
