Having "unresponsive script" problems constantly. Have to manually shut off computer (force quit won't even work) and go through a clean-up process.

iMac with OS10.6.8

Typed "about:config" in the location bar per https://support.mozilla.org/en-US/kb/warning-unresponsive-script

There is no "dom.max_script_run_time" preference.

So, what do I do now?

Thank you

Did you roll back to Firefox 26 to try to solve this problem? The current version is Firefox 31. https://www.mozilla.org/firefox/all/

Have you tested in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • (menu bar) Help > Restart with Add-ons Disabled

Not all add-ons are disabled: Flash and other plugins still run

After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (not Reset).

Any difference?

Please update to the current Firefox 31 release.

  • Firefox > About Firefox

The Firefox 26 version that you currently run is no longer supported with security updates.

  • It is important to update Firefox and add-ons to the latest version to get all security fixes.

--- Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox > Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
