Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
options.xulwas missed from version 1, which causes logs in Error Console, and make useless the detail page of the add-on.
options.xulfile was left out from this release,
which breaks Addon Detail page in FF7+.
So I decreased compatibility to FF6.
Updated release was pushed to the Review queue.
