Google has just released a new version of the google toolbar for Firefox! With some features that include subscribing to feeds using your favorite reader (there is a small selection of readers) and more!
We’ve made searching better by including previous queries, spelling corrections, and suggestions for popular choices. Gmail fans might appreciate having the mailto: links in Firefox open a compose window in Gmail -– no more copying and pasting email addresses. And to combat the ever-increasing threat of phishing, we’ve integrated the Safe Browsing extension into Toolbar to alert you when a page is trying to steal sensitive information.
