Not for Thunderbird Rated 1 out of 5 stars
Even though this is listed under a Thunderbird (email) addon, it only works with Firefox.
It would be nice if it allowed words and phrases to be highlighted in Thunderbird emails (going and coming).
This is not a Thunderbird add-on
Hi, there seems to be some confusion here - this has never been listed as a Thunderbird add-on, and I've never supported Thunderbird. I hope you find what you're looking for.
