Rated 4 out of 5 stars

Excellent and very useful product. However:
1) Why does Firefox show Hebrew Calendar 1.0.6.6 as "unverified"? Previous versions show as verified. Why not this one?
2) As several other reviewers mentioned, the Hebrew days-of-week are NOT "yom aleph, yom bet, yom gimmel...", but rather "yom rishon, yom sheni, yom shlishi...".

This review is for a previous version of the add-on (1.0.5.09.1-signed.1-signed.1-signed).
