When I compose a message in Thunderbird that contains an inline base64-encoded image (for example, an HTML
), the image is correctly visible in the compose window.
However, after sending the message:
Other mail clients and devices display the inline base64 image correctly.
In Thunderbird (both in Sent and Inbox folders), instead of the image there is just an empty placeholder/blank space.
Steps to reproduce:
Compose a new HTML message in Thunderbird.
Insert an inline base64 image (e.g., copy-paste from clipboard or manually via
).
Send the message.
Open the sent message in Thunderbird or receive it on the same Thunderbird client.
Actual result:
The inline image is not displayed — only empty space is shown.
Expected result:
Thunderbird should correctly render base64-encoded inline images, as other clients do.
