Review for Thunvatar by Ed
Rated 4 out of 5 stars
The Favicon checkmark in the column selector menu sometimes gets unchecked when either changing folders and returning to Inbox, or when closing and reopening Thunderbird. The result is that no favicons are showing until Favicon is selected again in the columns menu. This is with Thunderbird 102.8.0. (Sorry, but couldn't find a place for bug reports on your support pages.)
