I run a video site and users tell me they can not currently see my mp4 videos in Quicktime in browser pages in Firefox 3.5.5. I am experiencing the same problem on my computer.
The same videos are ok in Safari
Is it my site configuration or something else? I have had the same experience on some other sites, but not all.
I have spent a significant time in search engines and gained some insight but no definitive answers that sort this out.
Surely there's a simple answer.
A small trouble shooting job for the right service provider.
I have 30 x 10/10 feedback. I look forward to working with you.
