Firefox: Warning: Unresponsive Script

One problem I’ve been running into with the new Firefox 1.5 version is this annoying popup box that says “Warning: Unresponsive script. A script on this page may be busy, or it may have stopped responding.” There are two buttons, Continue and Stop Script. The thing with this box is that it comes up whenever you’re doing a file upload, like the ones I use in the Photos From Around Carson or on Flickr. So if you’re uploading a picture, and it ends up taking a little longer than Firefox likes, it stops the upload and flashes this box. You click on Continue, then after a little while Firefox flashes the box again. While I’m sure there are legitimate uses for this, like if a script gets caught in a perpetual loop or something like that, it comes up far too long during normal, day-to-day use.

So I found out from LifeHacker how to get rid of it.

  1. Type about:config in Firefox’s address bar.
  2. Filter down to the value for dom.max_script_run_time.
  3. Change the value to something higher than the default (which is 5.) I set mine to 20. [I did 100 –Scott]
  4. Bask in interruptionless browsing!

This should have been set higher by default, but what are you going to do? Maybe in Firefox 2.
