1872310 - Cannot Save JSON when opened from a blob Object URL

Status: RESOLVED DUPLICATE of bug 1872307

(Firefox :: File Handling, defect)

Description

[websitemakingguy+1]

Attachment: failed.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Create a JSON blob URL in JavaScript.

URL.createObjectURL(new Blob([JSON.stringify({test: 1})], {type: "application/json"})) 

When I open the URL created in a new window, the data displays correctly.

Actual results:

However, when I click save, the save dialog appears and I enter a name for the file. However, when I click "Save", the download dialog reports the download as "Failed" and the file never saves. Instead I have to manually copy the contents of the JSON to a text editor and then save the file that way.

Expected results:

The file should download successfully.

I can also reproduce this issue by opening a local JSON file in the browser and attempting to save it. It will fail. This appears to be a duplicate of bug 1872307 as it does not matter whether the JSON blob is created as mentioned in the description. If you believe it to be a different and separate issue, please try to explain why. Thank you.
