The problem is not only with Firefox and it happens I am not only using
Firefox.

Is there a similar blocking feature of Opera that you can suggest ?

Also in Opera:

   Uncaught exception: Reference Error: Undefined variable: fixBrokenLink
   Error thrown at line 39, column 5 in init() in
http://dev.w3.org/html5/spec/Overview.html: fixBrokenLink();
   called from line 1, column 0 in <anonymous function>(event): init()

I haven't reviewed the complete script itself but I have some thoughts about
this (comparing behaviour on different browsers).

I suspect that when the above is fixed it will take more time in Opera and
other browsers throwing errors and (maybe) suspending execution. As a side
note, should the browser completely suspend script execution when an event
handler fails ?

Isn't the error thrown in a different execution context when handling event
listeners ?

I believe the main execution context should not be suppressed, especially
for an undeclared variable in a different context.
