Many Javascript errors in Windows Firefox

[laria]

I have noticed in recent weeks that several areas of the forum have stopped working at all for me. These include:

1. Clicking on the multi-reply buttons in a thread.
2. Using the inline quick-edit post editor. It goes directly to the advanced page when I click on the button.
3. Clicking on the smiley images in the post editor to insert smilies into the post.

I finally went poking around in my error logs (I am a web developer by profession, so I'm pretty used to doing this sort of thing) and I get tons of Javascript errors when pages load, which would appear to be what my issues are.

When I load a forum page I get:

Error: vBulletin is not defined

When I load a thread page, I get many of the same errors above (different line numbers), but also:

Error: fetch_object is not defined

Line: 65

Is there something that was updated recently in the site code that would be causing these errors? I don't get them on Safari or Firefox for OSX, or on IE for Windows, just Firefox for Windows.

looks like JavaScript errors specific to you

It doesn't look like your browser is loading this file properly...not sure why...

It seems like the Javascript I had cached was bad for some reason. :o I disabled my cache with Firebug to force it to get a new copy and the errors went away.
