Mozilla.org has released a new release candidate version (1.5rc2) of Mozilla, its Web browser for Mac OS X. The new version adds an integrated spellchecker for Mail/News and Composer, custom email headers, improved Composer functions, better tabbed browsing, and an updated Gecko rendering engine.
Mozilla is an open source Web browser, designed for standards compliance, performance and portability. Mozilla is freeware from Mozilla.org, the organization that coordinates Mozilla open source development.
The latest released candidate may be the last one before version 1.5 is finalized.
