In Thunderbird, while composing an email, how to convert it from plain text to HTML? In general, I'd like to compose plain text emails by default. But sometimes, when I realized I need to insert HTML-supported elements in the email currently being composed, how do I convert it to HTML? If possible, after the current email is completed, I still want plain text email composition by default.
I agree with the comment above that it's not possible. However, it's possible to workaround.
Upon composing a plain text email and realizing that it should be in HTML, you can do the following (which I tested in TB on Win10)...
- Either hold down Shift and click the
Writebutton on the main TB window OR click
Newmenu on the Plain Text message window while holding down Shift. A new message window including a formatting toolbar should appear, where the presence of the formatting toolbar implies the format is HTML.
- In the Plain Text window, type Ctrl+A to select the entire message.
- Drag & drop the selection from the Plain Text window to the HTML window.
- Close the Plain Text window.
- Continue composing the message in the HTML window.
Of course in step 3, you can use any other copy & paste method if you prefer.
The simplest method, in my view, is:
- Ctrl+s or menu-item
File: Saveto save a draft copy of the current email under composition.
- Right-click on that saved draft in the Drafts folder and shift-click on the
Edit as new messageoption to bring up an HTML version of the email to continue editing.
- Discard the original email pane.
