You posted in the Firefox support fora queue. Firefox doesn't do email, it's strictly a web browser.

If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.

If your problem is with Thunderbird, let us know and we can move this thread to the Thunderbird support queue.

I'm using the email that Mozilla provides. I tried "web-mail" and the page wouldn't load, plus the most prominent text on web-mail was "This site may be for sale.

Please don't answer with misleading info just to stay in the "top 10 contributor" category. I want a real answer to the problem.

Can anyone else provide a real answer?

If Ed had not replied somebody else would have stated the Mozilla Firefox or Firefox for short is a web browser and not a email client.

The only way Firefox does email is by one of the many webmail sites out there as most ISP's for example have a webmail portal so you can use a web browser to view email. Gmail.com for example is one off the most well known webmail sites.

For example you registered with a yandex.com email address so the webmail or web-based email site for web browsers is https://mail.yandex.com/ and there is some troubleshooting help at https://yandex.com/support/mail/troubleshooting.xml

What a webmail or web-based email is. https://en.wikipedia.org/wiki/Webmail https://en.wikipedia.org/wiki/Comparison_of_webmail_providers

Mozilla.org does not provide any email domains for public use as any mozilla.org/mozilla.com email is only provided to individuals who work for or with Mozilla in some way.

If you are using the Thunderbird email client https://www.mozilla.org/thunderbird/ then you posted the thread in wrong section on https://support.mozilla.org/en-US/questions/new as this section is for the desktop Firefox web browser.

Thank you. Marked as solved.
