what version of firefox will support mp4 video tags without plug ins or extensions?


I have a web site that my users upload mp4 videos to my website. I use html 5 and use the video tags type movie/mp4. The only browser that has worked without any add ins, plug ins or extensions is safari 4.x and safari 5.x with quicktime. What version of firefox will support playing mp4 videos without any add ins or extensions?

That will probably not happen if there are codecs used that require a license.


Your above posted system details show an outdated Flash plugin(s) that you should update.
