Fix Firefox unresponsive script warnings

Posted by admin - 07/01/06 at 07:01 am

Ever since I upgraded to Firefox 1.5, I’ve been getting some unresponsive script warnings on sites that employ heavy Javascript like Gmail or Bloglines. Curious about it, I dug around and managed to find out how to fix the problem.

Firefox unresponsive script dialog

To fix it, you’ll need to access the hidden configuration page in Firefox. Just type about:config in the address bar and you’ll get a page full of hidden configurations which you can tweak till your heart’s delight.

In the ‘Filter’ box, type dom.max_script_run_time. This will narrow the options till only the dom.max_script_run_time option remains. Right-click it and choose Modify. A box pops up. Change the number to something bigger like 20. This is the maximum time a script can run before Firefox considers it ‘unresponsive’.

If you can’t find the string in the about:config page, create it by right-clicking anywhere and then choose New—> Integer and enter dom.max_script_run_time. When prompted for the value, use 20.

So far I’ve not had anymore unresponsive script warnings, so I guessed that fixed that problem! However some extensions may also cause similar problems. Hope this helps.
