Rated 4 out of 5 stars
Almost perfect. The Firefox version is great. The Thunderbird version's toolbar icons are not consistent and only sized for small icon setting. Higher quality TB icons that match the theme would be great.
The Office Options addon does not seem to be downloadable on its page.
Thanksfor the feeback
There was an issue with the Office Options page and download. I have reported it to AMO - hopefully it will be addressed shortly.
Regarding Thunderbird icons. I completely agree. The issue is that the large icons are 24x24 rather than the standard 32x32 in windows. I have not figured out a way (as I am not overly graphically inclined) to correct.
