All of a sudden I can't connect to several sites . I get this message : failure to set up flash JSON.stringify cannot serialize cyclic structures. I don't know if its a new update or what . I have done a clean reload of my osx10.75 and it still does

Thank you for responding. I have 3 Mac computers . The macbook works fine and it has the same plugins as the iMac that I have the issue on. I have tried Firefox on the iMac and get the same message . I have tried Chrome and the window for the cam is just black , no message . Yeet on Macbook pro and my iPad and iPhone 6 no problem. I have gone as far as reloading OSX Lion twice. i have erased the hard drive completely and reloaded the system clean and before adding any files it still didn't work. I then erased the drive again and I did a complete secure cleanup tot DOD standard just in case there may be a virus or malware hiding somewhere. It still has the same problem after another clean reinstall. The URL is  Live Webcams | Tahoetopia

or tahoetopia.com/live-webcams/traffic . It says its run by J W player. I had no problem until about 8 days ago and I thought it was a problem witht he site but then I was able to use it on other computers? Im lost for an answer but hopefully I will run into someone who may have an idea . I also left requests on the JW site and tahoetopia but haven't heard a thing from them. Usually when its down they have a statement on their site  but there isn't any. Thansks for taking the time , and if you have any ideas I would love to hear them. If not have a happy holiday.
