When I try to make a new bookmark in firefox containing
 
location.href='org-protocol://store-link://'+encodeURIComponent(location.href)
 
as the location, the save changes button in firefox becomes inactive!
 
Fiddling around with the =' etc changin it to : makes it active but then of course the linkage from firefox to emacs goes
 
[This is WIN XP and firefox 3.0.8]
