firefox woes?

[Paula J. Lindsay]

Hi everyone,
I use mozilla firefox.  I am running RHE 5. I usually have several 
firefox sessions running on my main
machine. I noticed when I go to another machine, and log on using my
nis username and passwd, it says it can't open because a version is 
already running.  At this time, I
just use konqueror because I will be on the machine for just a short 
time.  Now, I have a user who
doesn't like this feature.  I've googled and looked through my 
thunderbird perferences and can't see
anything to turn off or on.  Does anyone know my answer?  I hope I don't 
get flamed for asking
a firefox question on a red hat forum.
Many thanks in advance,
Paula
