Downgrade Thunderbird 31.0

downgrade_thunderbird.mkd

There are a few issues in Thunderbird 31.0 that render Thunderbird useless to me.

1. Find available Thunderbird versions

• apt-cache madison thunderbird

1. Determine which version to use

• 1:24.4.0+build1-0ubuntu1

1. Downgrade to determined version

• sudo apt-get install thunderbird=1:24.4.0+build1-0ubuntu1

1. Send emails :D

Thunderbird doesn't much like downgrading add-ons, so be sure to manually search and install any additional addons Thunderbird doesn't install on its own.
