2 examples..VEVO and also any live feed like those on CNN,Fox News etc. YouTube seems to work ok
no errors but the video just never plays the play/pause controls never come up either.
No Problems when using Chrome. No problems with same versions on a Windows machine.
Using OSX 10.8.3, lastest Safari,Firefox, Flash. Attempted : uninstalled anti-virus, disabled firewall.. Restarted Firefox in Safe mode (no extentions), Reset Firefox. Uninstalled and reinstalled Flash.
Seems to be something differerent about certain types of video that wont work in either Safari or Firefox.
