Including 

br {position: absolute;} in a print stylesheet causes Firefox to crash when print or print preview is selected.

Reproducible: Always

Steps to Reproduce:
1. Add br {position: absolute;} to your print stylesheet.
2. Open web page with that has your print stylesheet call and a <br /> in the code.
3. Select Print or Print Preview

Firefox crashes in Firefox on Mac, windows XP and Ubuntu
Actual Results:  
Firefox crashes

Expected Results:  
Page should print or print preview should appear.

Putting as critical since it causes a crash, but most people don't position break tags, so not a critical bug as in a common bug, but critical since it causes a crash.

use of default theme, and default installations (Windows has no extensions added, ubuntu and mac had multiple extensions)

A testcase for this bug would be very helpful. Adding mw22 to the bug...

i put a page in my sandbox

http://www.evotech.net/sandbox/brfirefoxcrash.html

the last line in the print css,

br {position: absolute;}
 
when removed, does not cause it to crash


http://www.evotech.net/sandbox/brfirefoxcrash2.html is a page with the last line in the css (print2.css) removed

Wfm on trunk, I guess this was fixed by bug 509749 or bug 496742.

Confirming - testcase crashes  Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100105 Firefox/3.6 (.NET CLR 3.5.30729) quite easily.

Considering it does not seem to reproduce in latest versions and also considering the very old version originally affected, I will close this issue as worksforme.
