I have been working through the HTML5 canvas tutorial(s). Currently on Pixel manipulation: https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Pixel_manipulation_with_canvas, and hit on a problem/issue.

The issue concerns the canvas and getImageData() method. The workaround (when working with local files) seems to be to store and load the image from same directory as our HTML page. Not the most elegant solution, and I have similar issue with Google Chrome, but I am able to fix this by launching app from Terminal and setting --args. The issue is not present in Safari, (all on OS X).

Is there a similar (or better) way of launching Firefox to allow 'file-acces-from-files' locally?

I hope this makes sense. Many thanks in anticipation.
