Therefor we have to increase the default script run time on the browser.
1. Type "about:config" then press enter.
2. Filter the "dom.max_script_run_time" .
3. By default the value of the dom.max_script_run_time is 10.
4. Now you can set this value to suitable and possible value. (say like 20).
(if the value is 0 whole firefox wait for script to run , and it can not be use
while waiting .)
5. Then click OK and restart the firefox
Warning -Keep remember
The value of dom.max_script_run_time is should not be too large. Because it will help to run bug full script in your browser.
