Is this update a retrograde step?

[Graham Watkins]

Not so long back, I installed Firefox 3.5 from the Firefox website. 
I've been fairly happy with it.  Now the update manager wants me to
install the latest version of Firefox 3.0.  If I do, purely to stop the
update reminders, will it trash my 3.5 installation?  If not, is there
any way I can stop the update message ?

Cheers,
