Today Mozilla announced the launch of Firefox 8.0. The headline features this time around include adding Twitter as a search bar option, tab loading tweaks, and the default disabling of addons installed by third-parties. "Sometimes you download third-party software and are surprised to discover that an add-on has also installed itself in your browser without asking permission. At Mozilla, we think you should be in control, so we are disabling add-ons installed by third parties without your permission and letting you pick the ones you want to keep." Here are the release notes and download links.
