The Red Hat engineers disabled the ffmpeg capability of firefox a couple releases back due to stability issues. CentOS also has removed it as for our main repositories, we build the source code for RHEL with as few changes for branding/artwork as we can. That said, we (I :D) want a firefox with ffmpeg support available, therefore I have created a centosplus version of firefox that has ffmpeg enabled starting with version 45.4.0-1, released to the repositories a few minutes ago. You can get it from the CentOS Plus Repository: https://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus Now that we are maintaining a CentOSPlus Firefox .. if there are other things people want compiled into Firefox that are configure options and you are creating/compiling a new firefox, please use the CentOS-Devel mailing list to discuss this with me and we can try to roll those things into the CentOS Plus version of Firefox. Since CentOS-5 is End Of Life in about 6 months, I don't plan to add a Firefox to CentOS Plus there unless there are many who absolutely need it.
