A second minor bug found in the Firefox 2.0 browser will be fixed, but users shouldn't encounter much of a problem in the mean time, a Mozilla official has said.
"It's very unlikely that anyone would have put a similar page on any ordinary Web page," so users shouldn't be affected, Nitot said.
The problem can't be used to steal data from a computer, he added.
The new bug will eventually be fixed. "We will fix it because we need reliability," Nitot said, adding no timetable has been set.
Firefox 2.0 and Microsoft's rival Web browser Internet Explorer 7 (IE7), both of which debuted within a week of one another, are under close scrutiny by security analysts.
Both vendors have contested experts' claims of flaws. Mozilla said one reported problem with Firefox 2.0 was fixed in a previous version, while a second report of an exploitable vulnerability couldn't be replicated.
Microsoft charged that a behaviour cited as a vulnerability in IE7 - where a pop-up window can display content from a different, untrusted Web site - isn't a bug, but a feature after the behaviour was reported by vendor Secunia AsP.
