Windows – jQuery disabled on Firefox. I cannot enable it

firefoxfirefox-3.6jquerywindows 7

Last night, pragmatist Vaio Care automatically fixed (!) the errors on my Sony Vaio laptop and soon afterward, a big problem emerged. I start Firefox 3.6.16 and navigate to superuser.com (and other Stack Exchange sites) and the following warning appears:

Super User works best with jQuery
enabled

What did I try to fix it? Well, here is the list:

  • As I suspect Vaio Care 99%, I loaded the previous Windows restore point (yesterday, just before Vaio Care started its job). It loaded the registry to its previous state as well. Result: I got the same jQuery warning.

  • I checked Firefox' settings. JavaScript was enabled. I disabled/re-enabled it, restarted FF. No good.

  • I updated Java from Oracle's site to the latest version (6.0.24). No good.

  • I started Firefox in the Safe Mode. No good.

  • I uninstalled and reinstalled Firefox completely. No good.

  • I shut down the Windows Firewall. No good.

  • I checked Internet Explorer 9 if it works. IE9 works fine with jQuery. The problem seems to be related to Firefox probably (I'm not sure though).

So I spent all of my bullets. What should I do now to fix this?

I've just had the same problem on Linux, with Firefox 3.6, and solved it. I had just to force Firefox to redownload jQuery. Specifically, I clicked on the link given by Garreth, got an error from Firefox (something like "can't access the file", but from firefox) and pressed Shift-F5 (force reload) or maybe F5 (Shift-F5 is safer). The file was loaded, and Super User started working again. The poster did a similar step, among other things.

Does the jQuery .js file (the one specifically used by Super User) download at least in Firefox? ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js
