FF 3.6 problem:
I install the addon and it works.
I reboot my brand new Win7 laptop and it grays out the Smart addon saying it incompatible.
The update button inn the addon is grayed out.
I hit the Find Updates button on the addon popup and it find one.
I restart FF and Smart addon works again.
If I reboot, repeat of above.
