I installed the new tool bar for yahoo. I wanted to go back to the old style to get some information that did?

Look in the upper left corner of your Firefox browser. If you see a red-orange button with the words Firefox click the button, click Options. Click the General tab near the top of the Options Window and under Home Page click the box Restore to Default. Otherwise, click the Tools button on the Firefox Menu Bar, click Options and do the same as above for the Home Page. If your Yahoo toolbar is not showing you can reinstall at toolbar.yahoo.com. Click the gear icon at the end of the Yahoo toolbar, click Edit Your Apps, delete and/or rearrange your icons. If you want to add Apps click Add Apps (while under Edit Your Apps). Good luck.
