doesn't work. I changed the value from about:newtab to about:blank and when I open a new tab it still opens up my home page. Am I changing the wrong item? Thanks.

How are you opening as new tab? Are you clicking the plus button on the tab bar?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do not click the Reset button on the Safe mode start window or otherwise make changes.

If you are having trouble still, Reset Firefox, Refresh Firefox - reset add-ons and settings, then try to edit the new tab again.

Thank you, Tylerdowner. A reset was all it took. Now I get the blank page I wanted. Thanks again.
