I would hate to see this excellent extension go away because of changes at Firefox. Although Firefox is doing away with XUL/XPCOM and bootstrap extensions, Pale Moon is not! Pale Moon is a fork of Firefox with significant differences, including the commitment to "legacy" add-ons. I would love to see this wonderful add-on at the Pale Moon Add-ons Site. If you are interested, then contact Lootyhoof or FranklinDM at the Pale Moon Forum (use the private message function). You may want to read this information about submission, too.
