Google has changed the domain for signing in to accounts.google.com and the Google toolbar is still using the old and longer working www.google.com/accounts domain You will have to update that domain yourself by editing a file used by the Google Toolbar. *Go to the extension folder in the Firefox profile folder and find the folder with the Google Toolbar *Open up lib\toolbar.js with a plain text editor *Replace: www.google.com/accounts with accounts.google.com ----- You can also access the Google Bookmarks here: * http://www.google.com/bookmarks
