Firefox 3.0.7, the second security update this year to the open-source browser, fixes about the same number of bugs that Mozilla patched a month ago.
Other patches plug holes that could be used by hackers to steal private information and spoof URLs to trick users into thinking they're at a legitimate site.
Mozilla also addressed several non-security issues in Firefox 3.0.7, including unspecified stability problems, a bug that caused some browser cookies to mysteriously vanish, and a Mac-only flaw associated with the Flashblock add-on.
The new version of Firefox can be downloaded for Windows, Mac OS X and Linux from the Mozilla site. Current users can also call up their browser's built-in updater, or wait for the automatic update notification, which typically pops up within 48 hours.
In other Firefox-related news, Mozilla today said that it would change the version number of the next major update from Firefox 3.1 -- the moniker used since May, when the company first announced the upgrade -- to Firefox 3.5.
The change, which had been suggested by several developers, will "indicate [the] increased scope" of the update, according to meeting notes posted online today.
Last week, one developer called on Mozilla to bump up the version number. "That way we would more clearly communicate to users that this isn't just a minor update but a major step forward," said Simon Paquet.
Mozilla also modified the schedule for Firefox 3.1 Beta 3 -- it is too late in the process to change the beta to 3.5 -- today, pushing back the ship date for the oft-delayed preview from an earlier estimate of March 10 to March 12.
Firefox holds a 22% market share, according to browser data from Web metrics company Net Applications.
