After installing mozilla-thunderbird-bin 1.0 the ebuild outputs: * To enable Enigmail, you must install the Enigmail and Enigmime * extensions as root. Go to Tools / Options / Extensions and click * on Install Extension to install Enigmail in your Thunderbird build. * Restart Thunderbird after having installed both extensions. 1) Enigmail and Enigmime have been merged into one package since thunderbird-0.9. Therefore you must not install any enigmime package with thunderbird.1.0 2) On my machine it is not necessary to install enigmail as root first. Enigmail is installed into the user profile by default. Therefore you have to install enigmail for every user separately even if you install it as root first. I read somewhere, that the command "thunderbird -install-global <enigmail.xpi>" should install enigmail globally but it does not seem to work (at least not with thunderbird-1.0 and enigmail-0.89.6). Reproducible: Always Steps to Reproduce: There is a procedure on for installing enigmail globally (on many machines), perhaps it can be included into the ebuild for thunderbird-bin and used if USE=crypt is set? Mhmm, just now I tried that procedure and it works. But there is a drawback: It seems that enigmail is only registered in the users profile if the compreg.dat in the respective profile is deleted. Install Mozilla/Thunderbird and Enigmail on many machines If you have to do lots of administrative installs for employee workstations, without having to run Mozilla as root, visit a web page, and click on a button: 1. unzip the XPI's in the mozilla installation tree 2. delete compreg.dat in the components directory 3. append the following lines to chrome/installed-chrome.txt skin,install,url,jar:resource:/chrome/enigmime.jar!/content/enigmime/ locale,install,url,jar:resource:/chrome/enigmime.jar!/content/enigmime/ content,install,url,jar:resource:/chrome/enigmime.jar!/content/enigmime/ skin,install,url,jar:resource:/chrome/enigmail.jar!/content/enigmail/ locale,install,url,jar:resource:/chrome/enigmail.jar!/content/enigmail/ content,install,url,jar:resource:/chrome/enigmail.jar!/content/enigmail/ skin,install,url,jar:resource:/chrome/enigmail-skin.jar!/skin/modern/enigmail/ skin,install,url,jar:resource:/chrome/enigmail-skin.jar!/skin/classic/enigmail/ locale,install,url,jar:resource:/chrome/enigmail.jar!/locale/en-US/enigmail/
enigmail support has been removed from thunderbird as extentions are being broken out into their own ebuilds.
