Google Toolbar 5 for Firefox is released that includes similar features as of version 5 for IE5: support for Google gadgets, integration with Google Notebook, multiple profiles for AutoFill and synchronized settings. The Firefox version doesn't include all the features that are available in Google Toolbar 5 for IE: there's no find bar, pop-up blocker, Browse by Name because Firefox already has these features. Customizable layouts, highlighting search terms, Word Find and Google Docs integration are the four Firefox-only features.
If you use Google Toolbar on multiple computers, enable synchronization to save AutoFill profiles, custom button and other settings to a Google account. Since bookmarks and notes are saved to the same Google account, you'll see the same Google Toolbar anywhere you go.
