I have a coworker who loves sending large plain-text tab-delimited data files by e-mail instead of our network share. The problem is that Thunderbird hangs while it renders all of that text into the message view window, making my inbox unhappy for minutes at a time.

Ideally, I'd like to disable viewing of text/plain attachments above a few K, but if necessary I'd be fine disabling viewing of all text attachments and just rely on an external viewer. There wasn't an immediately obvious way to do this in Options. Is there a way?

clear View > Display Attachments Inline

...and I feel dumb for checking Options first but not any menus. Thanks! – UltraNurd Feb 17 '10 at 17:05
After doing this, the txt file I want to download appears to be gone. – mlissner May 6 at 18:09

Due to changes to the Thunderbird options dialog Molly7244's solution does not work any longer.

Alternatively you can edit the Thunderbird configuration under Settings > General > Edit config and set mail.inline_attachment to false.
