Since about Firefox 25, a second drawWindow() call targeting the same canvas erases previously drawn content. I see this problem on WinXP and Win7-32-Pro but not on Mac OS 10.9.x or Ubuntu Linux 12.04. I created an extension that demonstrates the problem (attached). The extension adds a "Run drawWindow() Test" browser context menu item that runs a simple test in a new tab. This problem affects our Page Saver Pro extension which uses up to three drawWindow() calls on the same canvas in order to add header and footers to images of captured pages. The problem does not occur with Firefox 24.0 or earlier.
