Status: VERIFIED FIXED

(Firefox :: Downloads Panel, defect)

Description

[PikeUK]

Drag and dropping an about: tab (e.g. about:newtab, about:config, etc.) to the download button downloads the associated XUL file.

Steps to reproduce:
1. Open a new blank tab.
2. Drag the new tab and drop on the downloads button.

A XUL file is downloaded to the Downloads directory.

This doesn't happen dragging to the old manager, and doesn't sound like a particularly useful feature to keep.

Pasting an about: tab into the downloads popup also seems to suffer the same problem... But maybe for another bug?

Indentation is off.
You can use url.startsWith(...) instead of url.indexOf(...) == 0.
