The first animation from left to right doesn't work well, leaving a strange trail. If you click on the button that takes back to frame 1, sometime it works better. I've tried placing both png and gif transparent image (the man icon) over the green background but I can't notice any difference. Also, I've checked the firefox browser support.
The animation just does not work at all.
Please let me know if that's a known issue or if there's a way to fix it. Thanks.
Hi, thanks for answering. I was running Firefox 20.0.1 on Windows Vista. Now I upgraded to 21 but it still keeps the funny trail. Anyway, I manage to solve the issue by giving a 99% transparency to the sprite at the beginning of the animation and it works fine both on Chrome and on Firefox. Thanks.
