This Thunderbird add-on allows users to modify the HTML code of their emails whilst writing them.
Using this extension is a breeze, although there are a few things to keep in mind. First, you can refresh the code by clicking on "Reload." Additionally, it's worth noting that while Thunderbird supports many HTML and CSS methods and properties, not all email clients will interpret them in the same way. This means that you may need to do some testing to ensure that your emails look good across multiple platforms.
Overall, the Edit HTML for Thunderbird extension is a useful tool for anyone who wants more control over the appearance of their email messages. With its easy-to-use interface and helpful features, it's definitely worth checking out.
