Tested on Firefox 3.6 and on 3.5.4 as well. You can try it here: http://ade.web.elte.hu/_1023LF.txt Reproducible: Always Steps to Reproduce: 1. Create a simple text file with 1023 LF. Maybe less is enough, I've tested with 1023. 2. Open it with Firefox 3. Now you can restart your Firefox... Actual Results: Firefox crashes
Testing on Minefield latest nightly build produces a hang, no crash.

I haven't been able to figure out what the unloaded modules are but hopefully it's not important.
Firefox 3.6.12 on Ubuntu just hangs.
It works good in Firefox 10.0, Windows XP. Maybe Someone Fixed it?
