I don't like the default homepage provided by Firefox, so I found an extension that can offer better tabs. But when I open Firefox, my homepage doesn't show the page provided by the extension. It's still Firefox's default homepage. Only when I open a new tab will the page provided by the extension appear. Also, the settings don't offer the option to replace Firefox's default homepage with the page provided by the extension. I need to replace the homepage from Firefox's default homepage to the tab provided by the extension.
