[jQuery] jQuery breaks LastPass extension

I'm currently developing a firefox extension, and I use jQuery. I've noticed that LastPass, anohter extension, doesnt seem to work properly if I include jQuery in my XUL file. I've tried using jQuery instead of $ and calling noConflict without any change. Any ideas?

[jQuery] Re: jQuery(this + child) ?

jQuery(this).find(a).toggleClass(highlighted); Works.

[jQuery] jQuery(this + child) ?

Is there a way to do what I describe in topic? For example. jQuery(.class).click(function() { jQuery(this + a).toggleClass(highlighted); }); This doesnt work. What im trying to do is to select all the a elements within this. Is it possible to achive that somehow?
