Hi Orville, Firefox itself doesn't keep that list, it sounds like a feature of the website you use to check your mail. Can you find it in there, or in their help pages?

If it's a popular free site, a support volunteer here might be familiar with the process, but otherwise, the mail website's support is more likely to have the answer.

This is a support forum for Mozilla Firefox. You will have to contact your e-mail provider for help. https://support.mozilla.org/en-US/kb/problems-with-email-how-to-find-help

Or are you talking about Thunderbird? https://support.mozilla.org/en-US/products/thunderbird

Thanks for your input. I have an att.net email account, which apparently routes through yahoo.com. as well. I'll check both out. Thanks again! Orville
