Firefox extension: how to display long description in: add-ons
How do I add a long description to my Firefox extension?
There install.rdf
is a tag in the file <em:description>
. But the MDN states documentation says that the content of this tag should be short:
Description
A short description of the add-on - designed to display the interface in the user. This description must match one short line of text.
I need to add information so that it appears in the window when I click the Show More Information context menu item in the add-on manager. How can I show a more detailed description?

From about:addons
each add-on has a "More" link. The information on the page displayed when this link is clicked is taken from the description that the developer wrote on the Mozilla Add-on website after it .xpi
was added to them . The first image from the Mozilla Add-ons site is also displayed.
Currently, the Advanced page is populated from the following (if the lower number does not exist, the next higher one is used):
- Description of the add-on from the Mozilla add-ons site
-
<em:description>
for add-in in add-ininstal.rdf
This is just the behavior that I have observed. I have not checked the source code to make sure this is indeed the case. The description from the Mozilla Add-ons site is used even if the add-on is currently running from a different version located on your system. In other words, if <em:id>
matches the one on the Mozilla add-on site, the site description will be used.
When the Advanced page is displayed, some requests for the information displayed are sent to / from https://addons.cdn.mozilla.net/user-media/addon_icons
. However, I did not see a network request for the text of the "More" page at the time.
