Hi Nanamons,
We would like to help you resolve this issue. But before I ask you some questions I want you to clear your browser cookies and cache.
How to clear your cookie and cache >> Go to FF > Tools > Clear recent history > Select Cookies and Cache > Hit Clear Now Button> Close your FF Browser.
Now open new FF browser and load the Site. If you still see that your browser freezes up then answer the following question, this is help us understand the problem better,
1) What version of FF are you on.
2) When did this problem occur first?
3) Do you see the issue as soon as you load the home page "http://www.quilitngboard.com" or does it start after you have visited a page or two on the site.
4) Does it happen when you logged in or while you are logged out ?
5) Is it consistent across the site or is it on particular page.
4) Have you by any chance seen any particular ad that runs always when your browser freezes ?
I am sorry for the inconvenience. We are trying out best to resolve this issue. Mean time I suggest that you should use a different browsers.
Thanks,
Bhavisha
