Did you try to update FF? Every time they want you to update screws me up big time. I usually stall as long as possible. They keep hounding you to update. They bugged me for a long time to download Firefox 12. They finally getcha by telling you that you will be very vulnerable and lose security features if you don't comply.
I finally gave in and downloaded FF 12. They added some MP3 Tube toolbar (that said something about Yahoo) that I hated. I couldn't get rid of it. I was almost in tears. I disabled 12 and tried to reinstate 11. Did that three times using different sites to download. There isn't any way to dowload 11 anymore that I could find. Then I happened to notice on my desktop that I still had the FF11 set-up icon. It worked! Now I have FF 11 installed again and am back to being bugged all the time about downloading FF 12.
While I was fretting and hunting for answers, I read that the MP3 thing is spam and has nothing to do with Yahoo!
Other readers suggested several ways to get it disabled, but nothing worked for me.
