I see that you are the main one attempting to solve these issues on macs, but I don't think a proper solution has been figured out. I have allowed the sites to use my camera, my browsers automatically have the latest flash update, and it still doesn't work. Any additional thoughts not copy/pasted?

Having already exhausted tried all previously offered without success:
(1) If you have not already done so, restart Mac and try again. If the problem continues, use your Mac's Disk Utility to repair permissions.
Then download and apply the latest Combo Update for your OS: http://support.apple.com/kb/DL1581
Repair permissions again immediately following the system restart that completes the Combo update.
(2) If you still have problems after properly applying the Combo, try Lion's Recovery feature http://www.apple.com/ macosx/recovery/ to repair your hard drive or, if all else fails, reinstall a fresh copy of OS X.
(3) Properly applying the Combo version of updates or repairing/reinstalling OS X should correct software problems. If your trouble continues after trying all the above, contact Apple or an Apple-Authorized Service Provider for help.
