Firefox does not support the MPEG H 264  mp4  format at this time  due to a philosophical disagreement with the closed-source nature of the format   To play videos in all browsers without using plugins  you will need to host multiple copies of each video  in different formats  You will also need to use an alternate form of the video tag  as seen in the JSFiddle from  TimHayes above  reproduced below  Mozilla claims that only mp4 and WebM are necessary to ensure complete coverage of all major browsers  but you may wish to consult the Video Formats and Browser Support heading on W3C s HTML5 Video page to see which browser supports what formats   Additionally  it s worth checking out the HTML5 Video page on Wikipedia for a basic comparison of the major file formats   Below is the appropriate video tag  you will need to re-encode your video in WebM or OGG formats as well as your existing mp4     lt video id  video  controls  controls  gt     lt source src  videos clip mp4  type  video mp4   gt     lt source src  videos clip webm  type  video webm   gt     lt source src  videos clip ogv  type  video ogg   gt    Your browser doesn t seem to support the video tag   lt  video gt    Updated Nov  8  2013  Network infrastructure giant Cisco has announced plans to open-source an implementation of the H 264 codec  removing the licensing fees that have so far proved a barrier to use by Mozilla  Without getting too deep into the politics of it  see following link for that  this will allow Firefox to support H 264 starting in  early 2014   However  as noted in that link  this still comes with a caveat  The H 264 codec is merely for video  and in the MPEG-4 container it is most commonly paired with the closed-source AAC audio codec  Because of this  playback of H 264 video will work  but audio will depend on whether the end-user has the AAC codec already present on their machine   The long and short of this is that progress is being made  but you still can t avoid using multiple encodings without using a plugin

FIXED IT   I was losing my mind over this one  Reset firefox  tried safe mode  removed plugins  debugged using developers tools  All were to no avail and didn t get me any further with getting my online videos back to normal viewing condition  This however did the trick perfectly   Within Firefox or whatever flavor of Firefox you have CyberFox being my favorite choice here   simply browse to https   get adobe com flashplayer   VERIFY FIRST that the website detected you re using FireFox and has set your download for the flash player to be for Firefox   Don t just click download  PLEASE PLEASE PLEASE SAVE YOURSELF the migraine and ALWAYS make sure that the middle section labeled  Optional offer   is absolutely NOT CHECKED  it will be checked by default so always UNCHECK it before proceeding to download   After it s finished downloading  close out of Firefox  Run the downloaded setup file As Administrator  It takes only a few seconds or so to complete  so after it s done  open up Firefox again and try viewing anything that was previously throwing this error  Should be back to normal now   Enjoy

In my case  this error      Video format or MIME type is not supported    Was due to the CSP in my  htaccess that did not allow the content to be loaded  You can check this by opening the browser s console and refreshing the page   Once I added the domain that was hosting the video in the media-src part of that CSP  the console was clean and the video was loaded properly  Example   Content-Security-Policy  default-src  none   media-src https   myvideohost domain  script-src  self   style-src  unsafe-inline   self
