I'm running Firefox 133.0.3 and Win11 Pro.

You have to check without outlook FAQ for those preferences since Firefox isn't Microsoft Outlook.

markwarner, I'm looking at the Firefox Settings, the General tab, down to Applications, which allows me to make a 'mailto' selection. A couple of weeks ago Mail was the default. Now, one update later, Outlook (new) is the default. These are options in Firefox, not Outlook. I'm talking about how I'd prefer to send an email from any browser page, nothing else.

mailto options is a Windows OS function that can use browser to send email.

alright, thanks

Thanks, James, that helped. The stuff in your link I had visited a lot, but I made my way to the default app page in the Windows settings, and was able to finally get this sorted out. New computer, new OS, so I'm going in circles at times.

thank you both
