I've just created an animated html5 ad for a client. It plays in all browsers except for Firefox. Funny thing though; the version of the ad stored on my Mac DO play in Firefox, but not the one on the remote server. Ideas?

Lint to the ad in question: http://sjoogfloyd.no/kunder/bh/html5/bjorkneshoyskolefredogkonflikt580x400.html Javascript: TweenMax.min.js from GreenSock

Just posting to say I see your Ad as linked in your post from when using Mozilla Fx46 on Linux, or Iceweasel =Fx38.5.0

I will test on Windows in due course

Interesting! I've just tested on Mac. Maybe this happens only with the Mac version?

Now tested on a smartphone using Firefox Android and again it works.

I know. It works on iPhone using Firefox too. The trouble seems to be with Firefox on Mac's.

Is the page source loaded properly?

Do you see any content on that page?

You can check the log in the Web Console for error messages and the Network Monitor (Tools > Web Developer) to see if content fails to load or is possibly blocked.

Use Command+Shift+R to reload the page and bypass the cache to generate a fresh log.

Hi Cor-el

Can't find any errors (I think). I'm not sure exactly what too look for in these tools you suggested though.

The network tool would normally show a series of green circles and timings as it reports the site loading, after you use Ct+F5 or the Mac equivalent. The web console will report various errors some of which may be unimportant, but some should give clues to the problem. cor-el will interpret the results.

The thumbnails expand when clicked, use Esc to minimise.
