Hello,
I would like to propose FireGPG for inclusion in Debian and Ubuntu. In order to do so, it is required to fix a couple of issues I discuss here briefly:
1) chrome/firegpg.jar: extensions distributed in Debian/Ubuntu usually have not a unique archive for chrome directory, but they provide such files in plain-text format. This way it is easier to apply patches and propose them upstream.
2) hstart.exe: as much as .jar archive, it is uncommon to have a binary file. It is preferred to have its source files to compile it at a later stage. It is possible to remove it from Debian source package, so it's not so hard to get rid of it (since GNU/Linux should not do use of it).
If you are interested in this matter, feel free to contact me anytime.
Thank you.
