Big Problem with Yahoo mail, or is it the computer??

[ramcclain]

My husband has an iMac, Fall of 08, running OS 10.10.5. He uses Firefox 78.15.Oeasr.
For several weeks he has been unable to access his yahoo mail there. I tried accessing in Safari on there too, but couldn't there either. Meanwhile he has been using my iMac OS 15.3.1, and accessing his yahoo mail fine on Safari (I don't have Firefox, and prefer NOT adding to mine). I also tried downloading Apple Mail on his computer, and using that to access his email, but that wouldn't work either.
I think it is the version of FF he is using. He is 86, very firmly set in his ways, and wants to use as is. Yesterday he got a message about 'automated activity (bots) on his network' when he questioned another website, & they included his IP address. IP 206.255.159/226
Could it be something with his IP address? Is there a way to change your IP?
I don't think FF can be upgraded on his computer. Am I correct? Very frustrated, and even have another computer, my old one, which will probably work, but he wants the one he has.
Anyone got any ideas or something else to try? Very frustrating

All of the major free e-mail services: Yahoo, Outlook Online, Gmail, have begun implementing enhanced security to log in. It's very frustrating for many.

I'd try logging in on this page specifically for Yahoo Mail:

https://login.yahoo.com/?.src=ym&ps...en-US&.intl=us&.done=https://mail.yahoo.com/d

Beyond that, I don't have anything to suggest beyond contacting Yahoo Support and asking for assistance.

Would he object to using an email client? I mean I can understand resistance to change especially at 86 but stuff does keep changing especially security. The latest the latest stable version is 137.0.2. There are a few free decent email clients out there but Randy's suggestion is probably the best bet if it will work with your husbands browser version.
If not see if you can update the version at all BUT be aware, if your husband does not have a Firefox (Mozilla) account updating may loose all of his settings, bookmarks ect.
