Uh...  Firefox does not load anything synchronously.

What Firefox does do is block execution of <script> tags (but not 
timeouts, callbacks, etc!) if there are pending non-altenate 
parser-inserted stylesheet loads.  This is necessary to make sure that 
scripts getting layout properties see the effect of those stylesheets. 
A side-effect is that a <script> coming after a <link> will never see 
the link in an unloaded state... unless there's a network error for the 
<link> or whatever.

OK.  That behavior is allowed by the spec as far as I can tell.

What specific changes do you want to the spec?  As far as I can tell, 
right now the spec says nothing about when sheets become associated and 
that this would need to be defined, right?  Anything else?
