Ubuntu – GPG Workflow in 11.04

At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website.

Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, rendering it unusable. With the launch of Firefox 5, FireGPG will no longer install.

Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling a large amount of these small files throughout the day this starts to become a real chore.

I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal.

So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.
