we have a training website which uses FlowPlayer to display videos which are MP4 files saved as web optimized. After extensive testing we have so many folks who are using FireFox and are unable to access all videos and or get error messages as follows:

HTML5: Videofilenotfound

After doing a few searches for solutions it seems this is a serious issue for many people with Firefox and Chrome. Both PC and MAC. We've tried all the solutions in adding tags, adjusting the htaccess file and nothing works. Ironically, IE 7-9 play the videos without a problem. So does Safari. Makes me chuckle as we normally anticipate problems with both these browsers.

There must be a solution or update Mozilla can offer to resolve this issue. Anyone have thoughts how we can resolve this? We have over 500 participants logging in for a distance learning training and have to specify not using Firefox.

Thanks in advance for your programming expertise.

Could you check Firefox's consoles to see whether you can get more detailed error messages when the video doesn't load?

  • Web Console (from Tools > Web Developer or try Command+Shift+k) -- this shows requests and responses, and clicking the URL shows the HTTP headers including content-type, which might be relevant.
  • Browser Console (from Tools > Web Developer or try Command+Shift+j) -- this is somewhat duplicative of the Web Console, but may show slightly different errors.
