Reproducible: Always Steps to Reproduce: 1. Open the above URL of a kaleidoscope animation in Firefox. You can use http://commons.wikimedia.org/wiki/File:Bouncywikilogo.gif as an additional test image. 2. Click on the image for a direct link. 3. Repeat steps 1 and 2 in another browser such as IE or Safari. 4. Install Greasemonkey and this user script: http://userscripts.org/scripts/show/72090 that slows down animated GIFs, multiplying all delays by a factor of 2.4. 5. Repeat step 1, observing the slowdown. (The script does not apply the slowdown to direct-linked images.) Actual Results: The animation is noticeably faster in steps 1 and 2 than in steps 3 and 5. The 2.4x slowdown applied in step 5 causes the frame rate to approximately match that of Internet Explorer and Safari (which are about equal). Expected Results: The animation should run at the same speed in all three browsers.
