A second minor bug found in the Firefox 2.0 web browser will be fixed, but users shouldn't encounter much of a problem in the meantime, according to Mozilla.

The browser will crash if it visits a web page that been intentionally coded with JavaScript in such a way as to target the bug, said Tristan Nitot, director of European operations for Mozilla.

"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.

It's the second bug that's been found in Firefox 2.0 since its release on October 24. The first bug also causes the browser to hang or crash when a very large document is loaded into an iframe - an HTML (Hypertext Markup Language) element - using JavaScript.

The new bug will eventually be fixed. "We will fix it because we need reliability," Nitot said, adding that no timetable has been set.
