Mozilla ships Firefox 31, adds search to new tab page

Gregg Keizer | July 24, 2014
Patches 14 vulnerabilities, beefs up malware blocker.

"Of the 327 URLs that the release version of [Firefox 31] did not catch, Chrome caught 286 of them," Mozilla said in admitting that its rival did a better job.

Also part of Firefox 31 were patches for 14 security vulnerabilities, four of them rated "critical," Mozilla's top-ranking threat. Of the remainder, five were pegged "high," four as "moderate," and one as "low."

The bugs fixed were the usual mix of "use after free" memory flaws and buffer overflows, with odds and ends thrown in. Coincidentally, Mozilla patched a bug in Microsoft's DirectWrite -- the API is used to render sharper text in Windows Vista and later -- that could be exploited by hackers.

Google just added support for DirectWrite to Chrome 37's beta build last week.

Firefox 31 can be downloaded for Windows, OS X and Linux from Mozilla's website.
