User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624

if link-prefetching-in-background is active all mozilla-windows freeze and will
not even redraw themself. Waiting for a few _minutes_ did not give me my browser
back. Deactivating link-prefetching solved the problem and the site builds
itself in a few seconds.
Except the browser-window I had the mail&news-window open and nothing more of
Mozilla.
Browsing other sites freezes the browser for "only" 1-5 seconds instead of doing
prefetching asyncronously in the background like it's title says. (I wonder if
screen-layout is somehow done in the same thread as network-related work.)

Reproducible: Always

Steps to Reproduce:
1. active link-prefetching
2. open www.adac.de 
3. wait for it to happen

Actual Results:  
No mozilla-window redraws itself on screen.
No inputs are accepted.
Cannot close the browser without doing a killall from the text-console.

Expected Results:  
loaded the links in the free bandwith asyncronously in it's own threads.
Redrawn itself and reacted to inputs non-blocking.

there are no link prefetching directives in the page you mentioned.  loading it
worksforme (no hang).

the page has a flash plugin.  what version of flash do you have installed?

Reporter doesn't say anything, so...
Reopen if your opinion is different and you are able to reproduce this with a
current build.
