Each time I open a new tab, it opens in Firefox, instead of my home page.

Hi Phil

This support article should help you to set the new tab page in Firefox:

Thank you for your reply. However, I already saw that and tried it. It doesn't matter if I choose Firefox home or extension, I get the same thing. The only difference is that one is in dark mode and the other in light. I have to click on the Home icon to get the page that I want. I'm attaching 2 screen shots. One showing the default when I open a new tab. That's the Firefox page. The other shows what I want to appear. That's the DuckDuckGo search engine.

The first purple image is Private Browsing https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history

The default Homepage in the desktop Firefox web browser is Firefox Home which is about:home

Thank you. That is good info. But how do I get it to default to the darker image when opening a new tab?

Dark image is under Settings > Appearance

Home page via Settings > Homepage and startup > Home page > Custom URLs
