No Message Pane Sort
No Message Pane Sort prevents accidental resorting of the message pane by disabling mouse button clicks on the column headers, thus, locking the sorting order of your emails.
It is still possible to sort messages by ctrl-clicking the header.
No More Install Delay
UPDATE: XPI delay has been removed in Firefox 40!
Disable the install delay in Firefox. New 2.0 version now includes GreaseMonkey scripts!
Unlike similar addons, this works on Firefox 4 and beyond.
