More often than not, you can find this extension helpful if you have compatibility issues with other extensions after upgrading to Firefox 5:

• https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/

Most addons are likely to work, since this release doesn't have many major changes that would affect some addons that modify the interface. However if you find that Yahoo Toolbar doesn't work with Firefox 5, please contact its developers and notify them of the problems you have.

Thank you. :-)
