Suddenly, I was unable to access Hotmail or another email account that uses Outlook. The message I received was: "JavaScript required to sign in. This web browser either does not support JavaScript, or scripts are being blocked."

1. Why would this spontaneously happen?

2. How do I fix it?

You can check the javascript.enabled pref on the about:config page.

There are also extensions that can block JavaScript or otherwise interfere.


You can try some basic steps in case of issues with web pages:

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • Hold down the Shift key and left-click the Reload button
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Command + Shift + R" (Mac)

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 > Cookies: "Show Cookies"

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

  • Do NOT click the Reset button on the Safe Mode start window.

The about:config solution worked! Thank you very much.
