    Holy cow!

    I’m a smart cookie but never thought of this – and so many others are having this problem when attempting to view video from sites whose .htaccess files do not contain these entries. I had gone to so much trouble. Was so proud of myself for creating video in so many formats that ANY device should have been able to view them. Even IE7 could view the videos on XP!!! – So, imagine my shock when version after version of Firefox on platform after platform failed to load my videos…

    Until your quick, painless solution.
    This solution should rank MUCH more prominently on Google results.

    But then, we all know that Google is a raging monopoly that needs immediate disassembly like Microsoft got. Obama? You listening?

    I am a novice here, but I have a problem viewing video lectures on firefox and ie9. it seems that your solution should be working for my problem, too. I don’t know what is .htaccess file and how can I create one so that those videos (on some websites which is not mine) be played on my pc. Can you give me a hint?

    Thank you,

      The short answer is that you can’t.
      A .htaccess file is a directory-level configuration file supported by several web servers, that allows for decentralized management of web server configuration. This file can be made only by the owner of the site. Perhaps you have other problem, and you don’t have video player or something on your computer.
