Enabling Java Support

more options

I am taking online classes for college. I have been using Internet Explorer but the program that we use for our classes has to be with Firefox, which I haven't been able to use because it won't even let me login to my school website. It says that JavaScript was disabled and I contacted my system administrator and she couldn't even figure it out. I have done and read a million different things and I still can't figure it out. I have a DELL Inspiron 15 3000 series.

It would be rare for JavaScript to be disabled and not hear about it from 75% of the sites you visit. Still, you should check the setting if you haven't already. Firefox just has a single global on/off switch for JavaScript here:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste java and pause while the list is filtered

(3) If the javascript.enabled preference is bolded and "user set" to false, double-click it to restore the default value of true.


If the above doesn't help...

Sometimes a website will say that JavaScript seems to be disabled even when it is enabled. Possible causes for this are:

  • A script that starts a plugin, such as Flash, is not working, and the script simply identifies the problem incorrectly
  • An add-on is filtering the page, for example, blocking some scripts or ads, and another script in the page detects the missing element and identifies the problem incorrectly
  • An external program such as a security suite is selectively blocking some scripts, and another script in the page detects the missing element and identifies the problem incorrectly
