There's nothing specific action need to reproduce this. Reproducible: Always Steps to Reproduce: 1. Go to the website http://www.kitty-yo.net/index2.php 2. Firefox will now crash. 3. If you open this URL with the Konqueror Browser (Linux), not the whole browser but the plugin (libflashplayer.so) will crash. Actual Results: Firefox crashes. All opened windows and tabs will be closed! Expected Results: Firefox should let only crash the plugins, not itself when a plugin has an error. The error seems to be in the libflashplayer.so, so the main error is on the side of Macromedia - but Firefox should not crash if a plugin does... I tried to reproduce this bug in the Firefox running on Windows, but there the crash didn't happen - perhaps because I'm using the 7th version of the flash plugin there and only the 6th version on my Linux computer, I will soon install the newest version of the flash player to see if the problem is there also. But all in all Firefox shouldn't crash if any plugin has an error.

Did you try it with FF1.0RC1 ?

It happens the same to me but with the Java plug-in. All the instances of FF are shut down when an error in the plug-in. FF should not crash because of a plug-in malfunction. I use a recent build of FF for Windows. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050113 Firefox/1.0+
