I have recently have started getting the following alert when trying to play a video or access messages within a twitter message I received on my Thunderbird messages - "This file does not have an app associated with it for performing this action." It won't let me play the video or go to the embedded tweet. I can open and read the original twitter message received, but cannot go to anything contained within it. I use to be able play videos or access messages within a twitter message with no problem, but suddenly I cannot. I have the twitter app on my computer and can play these videos or access the messages if I go directly to them on Twitter or through my web browser, but not from Thunderbird. How can I fix this?
