Since upgrading, I get a Javascript Error popup on every site I try to visit.

Posted

Since upgrading to Firefox 17.0.1, many webpages spawn a popup ( or several popups) with a very vague error message: [Javascript Application] Error: Syntax Error . It makes using the browser kind of impossible. Any ideas?

Chosen solution

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Reset Firefox – easily fix most problems article.
