Thunderbird 20 Beta 1 Released


Mozilla released the first Beta for the upcoming Thunderbird 20 on March 8th, 2013. Lightning Users: if you are using Google Calendar with Lightning, you should wait on this update. Either Thunderbird 20 Beta 1 or Lightning 2.2beta1 seems to break the Google Calendar integration (even with version 0.18 of Provider for Google Calendar extension). Users will be continuously prompted to enter their Google Calendar (gmail) password, which suggests there is an authentication or communication issue between Thunderbird and the Google Calendar server.

Fixes in Thunderbird 20 Beta 1 include Emails can now be sent to IDN based email addresses (bug 127399) along with various fixes and performance improvements. Thunderbird 20 (numbered as 17.0.5) is scheduled for release on April 2nd, 2013.

    Installed 20 as the update became available this morning.
    All text disappears from the 3 major areas in the client window leaving only a ‘mail toolbar’ and ‘menu bar’ visible.unless I disable all add-ons on start-up each time.

    This one seems to be the problem:

    Known Issues:

    WARNING: If you are uninstalling the extension, make sure to first set the Layout to Classic or Wide Message or Vertical otherwise you will see a grey screen of death on restart. Only necessary for Thunderbird 8.* and earlier versions.

    I haven’t played with the known issue work around yet.

    Many thanks, E.G. I couldn’t get add-ons to appear so that I could disable them without some fiddling around, I was going to just scrap it all but your nudge set me at it again..
