Updated fix version compatibility to 20.*, so FF13 is OK.
Here is the new XPI link: https://github.com/downloads/ath0mas/mozilla-firefox-addons/gmail_manager-0.6.4.1.6-fx+sm.xpi
... sooner or later, I may switch to Erik Nedwidek GitHub fork as GmailManagerNG should be a more evolutive solution for us all
