The only workaround is to select the message body, then go to Tools->FireGPG->Encrypt.
It's cumbersome, but works.
You'll also need to make sure GMail is not sending in Plain Text, and not Rich Formatting.

Topic: GMail message composition is broken? (19 replies, posted in Bugs & problems)
Message decryption seems to work, but there are no FireGPG controls in the compose window, and I receive this error message:
checkDock/compose chrome://firegpg/content/Webmails/Gmail/cgmail2.js 669 children[0] is undefined
I'm running FireGPG 0.7.10 (rev 663) on FireFox 3.6.2, and this problems seems to have started today (25 Mar 2010)
Any ideas? Thanks!
