It works pretty good when changing *.md to *.mdown on Linux, great!

Where can I report a bug for this addon? I can't find the right place, neither can I connect the writer.

I can't use it, when I open a *.md file, firefox always popup a dialog and ask me to choose a behaviour. Could someone help me?

I'm using firefox 16.0.2 in Ubuntu 12.04.

Hello,
I assume it's because .md is an extension used for Machine Description files on Linux. If you rename your file to *.mdown it works. I'll try to fix this ASAP.
