This has been reported before. I also saw a report that recently the Yahoo site and the Mozilla site were offering different versions, but both versions were flawed.

I don't suppose Yahoo were able to point you to any official announcement or Yahoo bug report etc

(_{Someone else has already tagged this question with bug 1131604} )

Posts continue to report problems e.g.

No further information was given. Actually,I was surprised to receive a reply of any sort.

For people missing their bookmarks on the latest version of yahoo toolbar , I actually received a response from Yahoo today. "Hi , We are aware that some users are unable to access their bookmarks in the Yahoo Toolbar. Our engineers are working on a fix to restore this functionality as soon as possible. We apologize for the inconvenience." So,this is not a Firefox problem. FYI.

Thanks for your "FYI (For Your Information) post.

Since you wrote yourself that this is not a Firefox problem I'll tag this thread as "offtopic" for Firefox support.

Please sort it out ???It's just a basic useless toolbar!

A problem Yahoo is apparently working on. So you would do better asking on some Yahoo site, and then providing the link to any Yahoo discussion, announcement or bug report.
