Edit HTML source
From MozillaZine Knowledge Base
- This article was written for Thunderbird but also applies to Mozilla Suite / SeaMonkey (though some menu sequences may differ).
The EditHTML extension lets you edit the source of a HTML message that you are composing.
Another way to do that is:
- Highlight the contents of the existing message (Ctrl+A or Edit ->Select All).
- Insert -> Html
- Edit the code as desired
- Press "Insert"
If Thunderbirds built in support for HTML editing doesn't meet your needs you could install the External editor extension and use an external editor.
