How can I make Firefox my default browse. I've tried various methods, but the next time I click on Firefox I get the message that "FF is not your default browser." One problem may be that before I close Settings, I don't find any "Save" button to preserve my choices.

Hi, it's a system setting. Firefox can launch the Windows 10 dialog to select your default browser, but it can't make the change for you. Could you compare the steps in this article to see whether they help on your system: Make Firefox your default browser on Windows.

Hi, I've read the article and have followed all the directions. The last instruction says "close Settings window to save your settings." I don't see any way to Save Settings before exiting Settings. Simply exiting Settings doesn't save those Settings.
