Many users have been having My Yahoo problems this weekend. Try this: (1) Remove your Yahoo cookies (save any pending work first). While viewing a page on the site (can be www.yahoo.com), try either: * right-click (or on Mac: Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Cookies" * (menu bar) Tools > Page Info > Security > "View Cookies" * click the padlock or globe icon in the address bar, click the ">" button, then More Information > "View Cookies" In the dialog that opens, yahoo.com should be prefilled at the top so you can remove the site's cookies individually. (2) Then try reloading My Yahoo using Command+Shift+r to bypass previously cached copies of the page. Success? ''It didn't work for me the first time, so I logged in using the Yahoo main page, then cleared cookies again, and it worked the second time.'' Note: the Refresh features moves your old profile (settings) folder to the desktop inside an Old Firefox Data folder. I suggest hanging onto that for a week or two in case you discover anything important is missing.
