The Mozilla Foundation has released the latest beta for Firefox 3, which includes more than 750 alterations and fixes.

The new beta includes fixes for memory problems that have been plaguing users, as well as a blocking system that will prevent the showing of pages that are known to be forgeries.

Anti-malware code is also being built in, and parents will have the option of blocking certain content.

Other improvements include automatic shutting down of outdated and insecure plug-ins, and easier removal of third-party applications.

The new browser is expected to go out on final release in June, but Mozilla is adamant that it will not be tied down to a release schedule if it means putting out buggy code.
