2012327 - WEBPs downloaded via GM.xmlHttpRequest are downloaded without prompting for a file save location.

Status: UNCONFIRMED

(Firefox :: File Handling, defect)

Description

[Jan M]

Attachment: userscript that demonstrates the issue

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:148.0) Gecko/20100101 Firefox/148.0

Steps to reproduce:

1: Use a userscript with GM.xmlHttpRequest to fetch a WEBP image URL.
2: Attempt to download/save the image using the response data.
3: Observe the behavior when the download is triggered.

Actual results:

The WEBP file is automatically downloaded to the browser's default download directory without any file save location prompt appearing to the user.

Expected results:

A file save dialog should appear, allowing the user to choose where to save the WEBP file, similar to how other file formats behave when downloaded via the same method.
