I'm sure there are a lot of people who have MULTIPLE email accounts (hence the need for an EXCELLENT add-on like X-Notifier). However, since GMail and others are on a 'security rampage', I'm always having to change (by force) my passwords just because I may log on from different locations (I travel a lot). Sometimes, I forget what I changed the password to and I need it in order to access account functions (beyond just having been logged in as X-Notifier does). So it would be VERY, VERY convienent if you could add a password "peek" function to X-Notifier.
Firefox lets you 'peek'
Are you aware of Firefox's 'Saved Passwords'? (Under Tools, Options, Security)
X-Notifier for Firefox uses Firefox's security management for its password storage.
