Decent extension; however the file naming convention could be better.
IE: -0.1.06-tb.xpi
Files that start with a dash is a special character in the Unix world. Removing files with that character can cause problems for new users.

To all Nix users to remove such a file (after installation) you can do:

rm ./-0.1.06-tb.xpi

Hope that helps some one.
3 starts because of non standard file naming convention; which cause new users issues when trying to remove the file.
