I can see the same problem on windows vista. Today, firefox upgraged to 2.0.0.7, and now, yahoo mail in unreachable. It is possibly a duplicate of bug 396673 and/or bug 396660

Works for me with 2.0.0.7 on Mac, XP and Vista, Arno, Paul, can you login into yahoo mail with a new profile ? (http://kb.mozillazine.org/Profile_Manager)

Yes, it works with a new profile. I also discovered it works in main profile after removing cookies every cookie related to yahoo. May the problem is on yahoo side ?

I just had this problem when trying to find a regression range from almost a year ago with yahoo mail beta. Kept telling I was not using a supported version even though I was. Even when I wasn't yahoo mail has always let me login with Minefield in the useragent.

This is the error I received: Yahoo! Mail experienced a login error: Login error: name:TypeError message:j has no properties lineNumber:648 fileName:http://mail.yimg.com/us.js.yimg.com/combo?/pim/r/dclient/g/js/core/40ed4e2d8d7c4fedfd40ff2da621022e_1.js&/pim/r/dclient/g/js/launch/8f7e5aa4beb78311833eddc3334a14e5_1.js Firefox 3.0b1 Vista Business OS

The new version of yahoo mail worked with the last version of 2.0.0.7 for me although I still wanted to use the old html classic version. When I switched to Beta 3 it wasn't working and I'd have to wait till the java errors messages came up to switch to classic from a pop up window. If I insisted to go to inbox the headers would be displayed but the content wouldn't. XP Beta 3.3 now and it still does the same thing. I suspect it is a java applet related issue within 3beta. For US yahoo users if your history memory is not deleted and you type http://us.f** where ** would be a 3 digit number most likely, the classic old version will come up. Switching to an other mail system is preferable to using IE any time! :) K

still see this?
