How to avoid the Unresponsive Script popup in Firefox with long running Javascript?

I want to benchmark some Javascript code in the browser, but it may trigger Firefox's "Warning: Unresponsive script" popup. This allows the user to click "Stop script" in the event that the browser is caught in a runaway function. While the pop-up is displayed, the currently running function has been halted. This isn't ideal, so is there a way to run my benchmarks differently such that Firefox doesn't popup this warning and ruin my results?

• You have to break up long actions into smaller ones and perform them in turns. This will also allow a better progress indication.

  spoulson : Can you elaborate? A simple example, maybe?

  Annie : Here's an example of using setTimeout to break up the running of the javascript: http://www.sonofsofaman.com/hobbies/code/settimeout.asp If you're doing benchmarks, make sure that you allow the code to run long enough to make up for the timer resolution.

• In firefox's address bar type about:config

  You want to change dom.max_script_run_time to be large enough for your scripts to run.

  Oded : Is he supposed to do that for every user of the page?

  Annie : He's using it for benchmarking--I don't think there are other users.

• You can use the script from this question to break processing long lists into smaller chunks:
