No Alt Text 0.1
Changes the default setting for new images to not use alternative text. This also works around a bug in some versions of SeaMonkey Composer and Thunderbird Message Compose whereby the Image Properties dialog would always demand alt text.
About this Add-on
Additionally the image properties dialog has a bug whereby it fails to realise that you have previously specified no alt text for an existing image. This means that it will nag you to set the alt text of an image, when you really meant to change one of its other properties. This extension works around the problem because it prevents the dialog from defaulting to alt text.
Thunderbird 6 has a workaround for this bug in that the alt text will default to the same state as the last image that you edited. Future releases of Thunderbird and SeaMonkey will contain a fix for this bug.
