Firefox Gaffe Prompts Quick Fix

Bug hunter Kevin Han posted an issue that was later labeled as severe, the bug causes certain images in a web page to be poorly represented.

The error concerns the representation of vector graphics using HTML and JavaScript. Firefox reacts to the JavaScript method canvas.drawImage() with the exception of "NS_ERROR_NOT_AVAILABLE". The method drawImage() should render pixel images into vector graphics drawing.

The developers have already released an updated [nightly] build that fixes this problem, the Windows version can be found here, the Linux version here. The Mac build crashed in the MozillaAliveTest, the development team is investigating.

You can reproduce this bug by looking at

For Firefox, this shows the photos fine. However the title and photographer name are on a plain background, when instead, they should be on a background of a inverted copy of the lower portion of the photo.

If you see the plain white background, you have repro'd the bug.
If you see the inverted photo background, you have verified the fix!
