[Sage] Does Sage (1.3.6) actually work with Mozilla Suite (1.7.12)?

[Andrew Pike]

According to 
https://addons.mozilla.org/extensions/moreinfo.php?id=77&application=mozilla 
Sage requires/works with Mozilla Suite. I just installed Sage on my Win 
XP SP1 Mozilla 1.7.12 system apparently successfully (according to the 
xpi dialog) but can find no sign of Sage in any menus or Sidebar.

When I look in the support pages everything refers to Firefox which 
makes me doubt that it really does work with Mozilla. Can you please 
confirm?
