I have noticed this before. Sometimes in some browsers with a flash camera dialog box, you cannot press the ALLOW button to access the camera, microphone. The problem is already revealed here. You cannot click the "Allow" button in the flash memory of firefox , and Adobe is tracking the problem with this error http://bugs.adobe.com/jira/browse/FP-4656 .
The recommended solution sometimes works, but not always. Another workaround I put on the website is to set the left and right CSS fields in the flash container as follows:
margin-left: 0.5px; margin-right: auto;
Well, now OS X Lion is out , and damn it doesn't work! I even tried the Facebook profile photo receiver, which also uses a USB flash drive for taking photos. Also there you cannot press the ALLOW button. Same thing with YouTube VCR, etc.
What to do?
