How To Fix Unresponsive Script Warning In Firefox/Thunderbird

by

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.

Firefox Unresponsive Script Warning

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

Firefox About Config

  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

Thunderbird Configuration Settings

  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

Thanks I continually get hung up on unresponsive script. I was so mad I was going to track down the person that did this and yell at them but your steps are easier.

I have been trying for months to fix this problem. I followed the instructions here for firefox, and it did absolutely nothing to help.

For those of you that it DID help, I am glad for you. As for myself, Hotmail can go fuck it's self.

I've used Hotmail since the time when it wasn't even owned by microsoft, and it has now become completely unusable for me. Regrettably, IU am forced to use gmail now.

I found that there are separate config values for Firefox and Thunderbird; make sure you set both.

Thanks it was such a help..I was wondering whether the warning was due to some virus attack.Luckily found this. :)

Thanks so very much for your help with this. It was driving me bonkers. I would love to do a trackback to this article however, the blogging app I use doesn't provide that service nor can I do it through Haloscan. Can I have your permission to write about it and provide this link as reference where I got it from?
Cheers

Thankyou so much!
This has been irritating me for a long time to the point where I don't like to check my mail as it makes everything hang and become unresponsive.
1 google later and the problem has gone.
Thankyou thankyou!

Thanks - but I get this error all the time and when I check my interval was already set to 20.

I've also noticed that the error seems to be exclusively related to Hotmail, either just email or more recently the 'Live' messenger.

Further insights warmly received!
