I just made a clean OSX 10.8 install and naturally installed my favorite browser FF 17.0.1 Was goint to a page to see a quicktime clip and bam no video. Page in question was: http://www.apple.com/iwork/tutorials/#pages-msoffice I'm using the Quicktime X that comes with OSX 10.8 (updated actually to 10.8.2 now). I tested the same link in Safari and the video plays perfectly fine. I have been googling allot and tested lots of tips like removing the pluginreg.dat and following many tips found on below links but i seriously cant make it work under FF. https://support.mozilla.org/en-US/kb/quicktime-plugin-play-audio-and-video?esab=a&as=aaq https://bugzilla.mozilla.org/show_bug.cgi?id=611296 http://support.mozilla.org/en-US/questions/930099?esab=a&s=quicktime+dont+work&r=6&as=s Is this feature really broken? I see lots of people having this problem and no solution right now. Appreciate someone with some insight to dig into this problem and provide a solution or atleast confirm this is broken so we dont bang our head against the wall trying to figure it our :D ps. Please make sure you are under the same condition as i explained, meaning using Quicktime X and nothing more (like older quicktime etc).
