When I compose and send an email (I always write plain-text emails) in Thunderbird, it always truncates my sentences and adds line breaks in the middle of my sentences.
How do I turn this feature off? It is quite annoying to me.
For instance, when I send people long URLs, the URL gets cut in the middle because of the automatic line breaks.
I am using the latest Thunderbird 9 for Mac OS X
