jQuery UI and Firefox's Firequery plugin conflict

I use firequery plugin as a tool to help me with jQuery based development.

I am evaluating the jQuery UI with Firefox's Firequery and Firebug plugins turned on. I see a ton of error messages when I visit the jQuery UI Tabs and Datepicker sample pages on the jQuery UI site with Firequery turned :

missing ; before statement
[Break On This Error] ndow);
jquery.min.js (line 168)
jQuery is not defined
[Break On This Error] e[d][1].apply(g.element,a)}},contains:...b.ui.isOverAxis(e,d,i)}})}})(jQuery);
jquery-ui.min.js (line 17)

[Break On This Error] $(document).ready(function() { 

My question is whether these error messages are because of problems in jQuery UI code or Firequery plugin ?

I'm the author of FireQuery. I don't have time to investigate the problem, but some people already reported that FireQuery interferes with some pages and breaks their jQuery code.

You may answer your question easily by disabling/uninstalling FireQuery and checking if the page has the same issues. You may use Firefox profiles to test it independently on your current settings.

I have similar problems. My project is big and using a lot of JS libraries (38 different libs) with a lot of custom JS code. I found just problem in one:

jQuery UI library: http://layout.jquery-dev.net/demos/complex.html Test it with fireQuery, you will see bugs.

Problem was in variable definitions. jQuery also cause problems try: http://jqueryui.com/demos/draggable/ and drag div in sample
