Unresponsive script problem. Accessed about:config to reconfigure dom.max_script_run_time. It's not there?? What do I do now?
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.

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.

"Remove Cookies" from sites causing problems:

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.
