You should contact Yahoo support as that is their site and Firefox has no control what Yahoo does in their side.

What happens when you visit that page? I get redirected to the main page, probably because I'm not signed in. Are you able to sign in to Yahoo normally?

I just learned from another thread that Yahoo discontinued My Yahoo. It's even mentioned on Wikipedia (https://en.wikipedia.org/wiki/My_Yahoo).

I don't know the best replacement, but the r/Yahoo subreddit would be a good place to browse for alternatives and commiseration: https://www.reddit.com/r/yahoo/

Yahoo have stated that the classic Yahoo start page has been eliminated as of December 10, 2024

Thx folks! Don't remember getting notified that this was happening. Glad I gave up struggling and searching to try to get to my home page and posted the question!!! Very much appreciated for your answers. Karen
