It didn't work with 6.x. I rebuilt the beginning of April to CentOS 7. 
Didn't work, until I got rid of the default gspca_spca561, and used the 
gspca_spca508. Updated the beginning of this week, and didn't work until 
I went back to gspca_spca561.

Works 100% of the time with cheese, when I add that preload.

I was really, really trying to avoid installing chrome.

Been trying to join a test meeting in firefox, and it opens a new tab, 
and demands that I use the app.

Thanks for trying.... I may have to try chrome (really didn't want 
google scanning what I do to sell it.
