Using latest Firefox, tried IE as well
I'm using Firefox 11.0; error still appears ONLY with Yahoo! online email browser.
Tried Internet Explorer (V9.something). Flash didn't show up as an add-on. I reinstalled it for IE, got the "successful" message, but still doesn't show on the list of installed add-ons. The error doesn't occur with IE, but I don't know if that's because it's IE or because Flash is being ignored by IE.
I hope to be able to check this out from another computer tomorrow. But I still think it's another problem involving AT&T/Yahoo! and Firefox.
