Review for Signature Switch by Clive Page
Rated 3 out of 5 stars
Works as described, except there seems no way of specifying that the signature should come at the top, when you want to post a reply above the quoted text. This is a serious drawback for some users.
This review is for a previous version of the add-on (1.6.6).To create your own collections, you must have a Mozilla Add-ons account.
