Does anyone know how to highlight in the 65.0beta version of Thunderbird? I can change the color of text and the whole pages background color but I can't highlight specific text only. I searched for an add on and had no luck. All the add on's I could find stated that they are not compatible with the 65.0beta version. I frequently highlight text in email correspondence. I can do this in Microsoft word and every other email application I have used. I am resorting to saving my email in Thunderbird and opening it up in my old email application to highlight and then send the email. It's really annoying!
