Hello:

I recently changed to Mac OS X Version 10.9.5 and came with it Firefox 33.1.1. Now the 720p and higher resolution options are no longer available for Youtube videos. What should I do to access those options?

(Meanwhile, the Safari Version 7.1.7 (9537.85.16.12) on the machine has all the options.)

I'd appreciate it if you'd kindly tell what I should do.

Thank you,

R.

hi, please update firefox to the latest version (39.0.3 at the moment, firefox 40 is due to be released next week) as they contain support for "media source extensions" which is a prerequisite on youtube to play-back html5 videos in higher resolutions.

Update Firefox to the latest release
