[Sage] sage and firefox 1.5

[Steve in Tennessee]

I have been using Sage with the previous version of FireFox with no 
problems.  Found Sage to be the perfect client to read the various feeds 
of interest.  I updated to 1.5.04 of FireFox and now I can't add the 
correct version of Sage via mozdev.org.  FireFox keeps saying "software 
installation is not currently allowed click edit options to allow."

It opens the options box for FireFox -> Contents where the 
"Warn..Extensions" box is checked and mozdev.org and mozilla.org are 
both allowed as exeptions.

I have re-installed 1.5.04 and the problem persists.  I only use FireFox 
to use Sage.  Any suggestions as to the problem source?
