Firefox is slow to display pages on

I believe this is script-related, because disabling scripting (using the NoScript extension) solves the problem -- but then the site's functionality is severely reduced.

Reproducible: Always

Steps to Reproduce:
1. Go to with scripting enabled

Actual Results:  
The page is partially displayed, then Firefox seems to freeze for several seconds, then the page is displayed properly and works properly.

Expected Results:  
Long delays during page load/display shouldn't happen.

This is especially annoying on slow systems, e.g. Pentium III 1GHz. It's less noticeable, but still annoying, on faster systems, e.g. AthlonXP 2500+.

I don't think this bug is platform-specific, as I've seen it on both Windows and Linux.

I'm running a Bon Echo nightly as I write this, but this bug also affects Firefox 1.5.

That's very strange. It works fine for me.

Could you try it again, or could someone else try it?

I tried Venkman's profiling feature. It clearly pointed the blame at:

That script is originally from here:
This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME

You might as well go ahead and close this bug. The website on which I originally noticed the problem no longer exists.
