I'm not sure exactly when this behavior started, but I've noticed that when I click a link to an XPI file on a third-party web-site, Firefox no longer prompts to install the extension.

For instance, when I click the outlined link in the first screenshot, the second screenshot shows what happens.

Keazen oplossing

The latest beta XPI file is send as type binary/octet-stream. Firefox always downloads such a file.

You will have to install the extension via the about:addons page or drag the file in a Firefox window to trigger installation.
