Mozilla Corp. will probably release a Firefox update tomorrow to patch a bug in the just-released 2.0.0.10 version, according to the company"s bug database.
If so, it would mark the first time that Mozilla has released two versions of the open-source browser in the same week.
A bug in rendering "canvas" HTML elements worked its way into Firefox 2.0.0.10, the edition Mozilla released Monday to fix six other vulnerabilities. Canvas elements, which were first used by Apple Inc. in its Safari browser, let Web site designers dynamically render bitmap images in HTML. Firefox, Safari and Opera support Canvas natively; Microsoft Corp."s Internet Explorer does so with a plug-in.
All editions of Firefox 2.0.0.10 -- for Windows, Mac OS X and Linux -- break pages that include the Canvas element, and cripple at least two Firefox extensions, FoxSaver and Fotofox.
