Yes, JavaScript is enabled by default.

Make sure that JavaScript is enabled and isn't blocked.

  • The javascript.enabled pref should be true on the about:config page

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
