User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0.1 Build ID: 20120907231657 Steps to reproduce: For Twitter, Thunderbird truncates tweets after 140 characters, even if the tweet is longer than 140 characters when "RT @username" is appended. Actual results: Retweets that were created using Twitter's web interface do not count the "RT @username" portion within the 140 character limit. Consequently, it is common to have retweets that exceed 140 characters when "RT @username" is added. This is especially problematic when the tweet ends in a link, which is then truncated to e.g. "http:/" or "http://t.co/". Expected results: Thunderbird should display the whole tweet, and not truncate tweets after 140 characters.
