Firefox Surgery Bandaid Mozilla pushed out Firefox on Tuesday which fixed three highly rated security vulnerabilities, but a rather critical bug slipped through their test routines. The issue lies in the canvas.drawImage which is used by some extensions and websites to display images. An example of this can be seen here where a line graph is supposed to appear on the left side using the source image as the background. In Firefox you won’t see anything there.

Why is this such a big deal? Extensions such as FoxSaver and Fotofox use that property for displaying images, and without it the extensions will appear to be flawed. FoxSaver even warns users on the site not to upgrade to Firefox if they want the extension to work as expected.

To correct the issue Mozilla is rushing a new release of Firefox, version, which could be out as soon as tomorrow. The Release Candidate is already available for those who want to get the fixed build a little early.

So this means that we will have had two versions of Firefox released within days of each other. How often has this happened before? The closest back-to-back releases prior to this was between Firefox 1.0.5 and 1.0.6 which was a period of just one week, and in Firefox 2 the closest release period was between and which was about two weeks:

  • – October 24, 2006
  • – December 19, 2006
  • – February 23, 2007
  • – March 20, 2007
  • – May 30, 2007
  • – July 17, 2007
  • – July 30, 2007
  • – September 18, 2007
  • – October 18, 2007
  • – November 1, 2007
  • – November 27, 2007
  • – Tomorrow?

Needless to say it is not a common occurrence to have two releases just days apart. We’ll keep you updated on the official release in our Daily Downloads.
