Clipper 5.0.0.204582 does not work in FF8 Rated 1 out of 5 stars

I have:
removed the extension and reinstalled it twice, once from inside FF and once from the mozilla site.
uninstalled and reinstalled Evernote 4.5.1.5432
removed and reinstalled FF, once at 7.0.1 and the second time at 8.0

It says here to not post bug reports in reviews, but there is NO OTHER place to post bug reports, so here it is.

The button appears on the toolbar, the right click menu has *two* 'add to evernote' items, one of which has its own drop-down. The 'tools menu has an 'add to evernote' item.

None of them work. At all. There is no response, whatever, to any of the possible input items.

This review is for a previous version of the add-on (5.0.0.204582).
