When viewing the page I provided a link to (, I became really frustrated in trying to interact with it due to extremely slow respoinse from the browser when trying to scroll or change the text size with the mouse wheel.  

Reproducible: Always

Steps to Reproduce:
1. Visit
2. Try to scroll or change the text size. 

Actual Results:  
The page scrolls extremely slowly and font size changes are even worse

When the site has not yet stopped loading it scrolls laggy indeed.
But when loading has finished I can scroll down within less than a second and the same goes for font size changes.

Confirm that it takes a while to render, but once loaded scrolls normally.

Confirmed here as well. The problem is really "jerky scrolling while loading page". Changing the title.

Oh, i weren't allowed to change title, but I recommend someone with access to do it. :)

Do you still see this problem?  ... Using current version of FF (3.0.4), or 3.1 beta - beta 1 at ... or beta 2 available soon 

If you no longer see the problem please close the bug.

Scrolling is no longer a problem.

First time using zoom or "resize text" is still quite slow, but much more acceptable. The second time using the same text, it's quick and responsive,
