Yes, this will happen if you use the same .mozilla/firefox for 32bit and
64bit. To this day I'm still not sure exactly what file is the cause of
this, but It could be any of the configuration files such as
compatibility.ini, extensions.ini or xpti.dat, I see references to lib64
in all those as well as pluginreg.dat. I've always thought about
tweaking the build to have .mozilla/firefox-32 and .mozilla/firefox-64.

Another thought is if you're using a 32bit plugin, try nspluginwrapper
so you dont need a 32bit firefox. I forget if I added it to cblfs or
not, if not you're welcome to tackle it or I'll slap it in there as soon
as I can.

Same thing with Firefox 3.5, I have yet to install it.
