Firefox 8.0

In yet another deceptively numbered upgrade, Mozilla has released Firefox 8.0, whose rather minor changes are more easily understood if you think of it as version 4.4. Firefox 8.0 changes its handling of add-ons, disabling those installed by third-party programs by default and adding a one-time selection dialog to alert users to previously installed add-ons. Also new is the addition of Twitter to the pop-up menu in the search bar, at least in some locales. A new preference in the General pane lets you prevent tabs from loading until you select them, which speeds up startup but slows down access
later. In terms of Web standards, Firefox 8 adds or improves support for WebGL, HTML5 context menus, CSS hyphens, and WebSocket. (Free, 29.5 MB, release notes)
