This so called is a horrible "Downdate" (I know I just made up a word) not an Update" Worst toolbar Yahoo/Firefox has ever come up with!! Totally useless to me. Lost all my hard worked at bookmarks. (Thankfully they are still there when I do this suggested rollback - for now anyway). I'm reposting the below for mine as well as others use!
Easy FIX for this MISTAKE!!! For Firefox! Rated 1 out of 5 stars

Less than zero for this new toolbar. Please re-post this!
GOING BACK TO THE OLD VERSION, WITH ALL YOUR FAVORITE SITES STILL THERE!
To go back to the old version of Yahoo Toolbar, go to: (copy and paste)
Hit the add to Firefox, and install it, as soon as you restart it, you will have ALL of your old sites, (buttons) that you had before this update, BACK!
VERY IMPORTANT: Go to "Add-ons Manager" and in the upper right corner, you will see the gear sign, (next to the find add-ons search bar) click on the gear sign, and where you see, "Update add-ons automatically" UNCHECK IT. That way it will not update it, the next time you sign on. You will have to check with the other add-ons to see if there are updates for them, since you will now be doing it manually. It is definitely worth it, to have your old toolbar back! Also, when you do sign back on, you will see the "coming soon new yahoo toolbar" Just close it every time. No big deal.
I swear all of your old sites will be back!
RE-POST, RE-POST, RE-POST, THIS PLEASE!
