To import your Firefox bookmarks, just follow these steps:

1. Sign in to your Google Account using the Google Toolbar or by clicking "Sign in" on the Google homepage.

2. Click on the star or "Bookmarks" button on the Google Toolbar and select "Import Firefox Favorites" at the bottom of the drop-down menu.

3. You can now select and edit the bookmarks you'd like to import.

If you don't see the option to import your bookmarks, it's likely that you don't have the latest version of the Google Toolbar installed. You can install the latest version at http://toolbar.google.com/.

Please note that you don't need to uninstall your current version before installing the latest version.
