How To Fix Unresponsive Script Warning In Firefox/Thunderbird

Hi ,

I’m sure a lot of you have already experienced this unresponsive script warning in Firefox and I’m also sure that you get irritated every time you see this because it wouldn’t stop nagging you. Actually, the reason behind this problem is the JavaScript may take a little longer than its usual time to finish its activity and then the application (Firefox) will think that the script is going wild and will never be finished processing thus causing the application to freeze or sometimes, crash.

 

Luckily, there’s a very simple way to fix this problem and that is to increase the amount of time before a script is considered ‘unresponsive’; this can be done in both Firefox and Thunderbird. 

FIREFOX

 

1. In a new tab type about:config in the address bar and press Enter
2. In the about:config manager type dom.max_script_run_time in the Filter field
3. Double click the entry and in the pop-up box type 20 and press Enter
4. Close the tab.

 THUNDERBIRD

1. Go to Tools -> Options
2. Click on the Advanced tab on top
3. Click on the Config Editor at the Advanced Configuration options
4. In the Config Editor type dom.max_script_run_time in the Filter field
5. Double click the entry and in the pop-up box type 20 and press Enter
6. Close the window

Its done!! Now you wont be getting the same again.
