The java applet will not download and allow me to select my printer, so as to print my shipping label from the US postal service.

Also, can no longer use google toolbar, all my bookmarks with the ff 5.0, so prefer to go back to the ff 4.0.

Not a good idea to post a phone number in a forum. Anyone with access to the forum now has your phone number. Return to the forum, sign-in, click "Edit" to the right of your post and remove that phone number.


Many users have restored the functionality of Google toolbar by installing the Add-on Compatibility Reporter extension. Google needs to test the toolbar in Firefox 5 and change one line of their code to make it compatible with Firefox 5.

You either do not have Java installed or you have it disabled in Add-ons > Plugins. See if you have Java Platform SE version number installed there. If there and disabled, click the "Enable" button and try the site again. If not, install Java.

  1. Install or Update the Java plugin to the latest version.
