This message has been sent to the extensions's coder in last December and January 16th. No reply at all, I am uninstalling this extension and looking for another one.
Using your extension, I have 2 problems:
1- I am asked my master password when I open/close the CM window, or/and when I shutdown firefox EVEN if the "read only" features are not selected (none of the 3 options are checked).
2- When I open the CM window, window is locked at a strange size: Very high (no size in fact, it is higher than FF window), I can resize it only horizontally but not vertically. Moreover the upper part when I can see cookies shows only 3 lines, I can not make it bigger (resizing does not work on the part).
I tried changing the size in the JSON script, nothing changes.
