I have an error message that says A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see

Question

The exact and full message is:
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: https://fbstatic-a.akamaihd.net/rsrc.php/v2/yk/r/w50KHoJTfoZ.js:26
so, I have read the many other threads on this problem:
1. I just installed firefox for the first time - this happens on facebook and many other sites
2. I have reset firefox - did not fix the problem
3. I have checked all my extensions and plug ins for up to date
4. I turned off hardware acceleration
5. I tried disabling all my plug ins
6. I used to use firefox, but it started doing this and I was never able to resolve this and went to chrome.
I am using Win 7. No problem, ofr the most part, using IE or Chrome, I just wanted to try firefox again. Does it not work with win 7?

You can try to clear the Flash local storage and settings if the problem is with the Flash plugin.
*Windows Control Panel > Flash Player > Storage: Local Storage Settings
**Remove a specific domain: Local Storage Settings by site
**Remove all domains: Delete All and Delete Data
Flash Website Storage Settings panel:
