Mozilla has closed a security hole in its Firefox web browser that could expose information from insure websites to anyone gaining get at to the software program.

The flaw was set up in the New Tab feature of Firefox 13. That feature displays thumbnails of antecedently visited websites whenever a new tab page is created. Those thumbnails could curb confidential information from banking and other secured websites.

"The new tab characteristic that displays thumbnails of your favorite and recently visited sites in Firefox now omits seclusion-sensitive websites like banking Beaver State webmail sites," Mozilla said in a statement to PCWorld.

"The new tab thumbnails are based connected your browsing history and you can easily control the undergo by moving or deleting the thumbnails," it added.

While Mozilla believes it has solved the New Tab problem, some security experts think the root of the glitch may be challenging to address. That's because entropy from secure websites is routinely cached by browsers and has been for some sentence, according Sophos security expert Apostle of the Gentiles Ducklin.

Anyone with memory access to Firefox, or its cache information, could browse that entropy for sensitive data, He explained. E.g., everything in the cache of Firefox or Google Chrome can beryllium displayed by typing in the address bar "about:cache" or "chrome://cache/."

Although Mozilla has closed the New Chit loophole, it's still wise to set Firefox's history settings to clear its history when you close the software program and to clear its Recent epoch history after performing tasks that involve submitting personal identifying information.
