Rated 5 out of 5 stars
Forgive me for not remembering if it is Walnut or Walnut2 I just downloaded after FF upgrade to new version knocked the add-on out. Had the one of them for a couple years before new version FF and thoroughly enjoyed it. The warm woodtone color is appealing since it is both bright and cheery, and easy on my eyes.
It has life, the basic light blue is too sterile for my taste.
Of course my opinion of Walnut2 is in no way affected by my last name being Wood: right?
