Are you getting unresponsive script warning while opening certain sites on Mozilla Firefox browser? The Warning: Unresponsive script prompt is common in Firefox. It means a script (either from a website or an add-on) is taking longer to load and would hang your browser. Normally unresponsive script error is not a serious issue. But it’s frequent occurrence is annoying. Want to get rid of Firefox unresponsive script error message? If yes, read on to find a quick solution.
Solution to Warning: Unresponsive script problem in Firefox:
- Open Mozilla Firefox browser.
- Type about:config in the address box.
- A warning message will appear. Press the button that says I’ll be careful, I promise!
- The Firefox advanced settings window will appear. Go to Filter field (right below the address box) and type dom.max_script_run_time to perform a search.
- In the area below the Filter field, dom.max_script_run_time integer will appear. Double click on that preference name. An window will appear for entering integer value. Enter value 30 and press OK button.
- Now restart Firefox. The Unresponsive script warning should disappear from now on.
By the above mentioned modification, we just allowed scripts to run for a period longer than the default. The Warning: Unresponsive script prompt occurs when a script is busy or stops responding. If we allow scripts to run longer, the problematic scripts might get enough time to load and you may no longer see the warning message. Don’t worry about the modification. It won’t break your web browser. Also, you can reset it anytime. To undo your changes, simply follow the above steps from 1 to 4. Then right clicking on the preference name and select Reset from the menu.
