[Sage] Sage 1.3.10 doesn't work under FF 2.0.0.1

[Max Hansen]

Yesterday I upgraded Firefox to 2.0.0.1.  Some time later, I was 
prompted to upgrade Sage.  I did so, and now have Sage 1.2.10.

Today, Sage doesn't work. At all. The feeds window is empty.  After I 
add a new feed, it's still empty (or perhaps I should say, when I 
click the add feed button after doing a feed search, nothing happens.)

I know I successfully used Sage yesterday, but I can't remember 
whether it was before or after the upgrade of Sage. I'm pretty sure 
it was after the upgrade of Firefox.

Yesterday I also installed the del.icio.us add-on.  I have 
uninstalled it to see if it was the problem. Sage still didn't work. 
I then uninstalled and reinstalled Sage. Sage still doesn't work.
