Google announced on Thursday the release of an upgrade to its toolbar for Mozilla's Firefox browser, including enhancements to the search box and an antiphishing feature.

Google Toolbar 2 for Firefox now offers suggestions to narrow down search queries and correct spelling. The search box also saves the user's previous query terms and bookmarks, and offers them up as suggestions to the user.

A drop-down menu furthermore lets users choose to run a search on different Google search sites.

The Firefox toolbar also comes integrated with what is called the Safe Browsing extension which was so far an optionnal add on. This feature alerts users when it considers a web page could be a phishing trap.

"As a dedicated Firefox user, I think that the latest version enhances an already innovative browser. Meanwhile, you IE Toolbar 4 fans may notice that the feature sets aren't identical. That's because Firefox and IE users have different needs," said Google software engineer Justin Voskuhl. "Rest assured that we're working to get the most popular features in both versions."
