[jQuery] error in jQuery?!


Hi guys,
I have a question. I'm using jquery on my pages and js files are linked
like this:
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script
src="http://dev.jquery.com/view/tags/ui/latest/ui/ui.datepicker.js"></script>
Everything works fine, but ff 3.0.1. is showing some(2) errors in
mootools.js:
el.set is not a function
el=$(el);return(!props||!el)?el:el.set(p...mentById(el);type=(el)?'element':false;}
($(filter) || document).getElementsBySelector is not a function
return
false;});return(nocash)?elements:...);}}else{temp.push('[@',param[4],']');}}
The first one I've seen many times and I really don't know, what is it
all about. The second one I've seen first time, but aparently, it
doesn't have any effects on running jQuery. Do you know, what's wrong?
Thanks, elf
