Mozilla released Firefox 8 this morning, continuing its pattern of small and rapid version updates.
In that spirit, one of the most interesting improvements is a small one — the integration of Twitter search as an option from the built-in search field. Another notable change is a feature designed to protect Firefox users from unwanted third-party add-ons.
In other Firefox news, Amazon.com announced that its HTML5-based Kindle Cloud Reader will now work in Firefox, letting people use the Firefox 6 and above to read Kindle books. Kindle Cloud Reader also supports Chrome and Safari, but not yet Internet Explorer.
Kindle Cloud Reader, available here, synchronizes with a user’s existing Kindle library, with features including the ability to start reading again in the browser at the same point where you stopped in a Kindle device.
