1423329 - Can't use file protocol in quick links

Status: RESOLVED DUPLICATE of bug 1401929

(Firefox :: New Tab Page, defect)

Description

[m.arthur]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171128222554

Steps to reproduce:

I have a .html file on my desktop, which I open with Firefox.
To have quick access to it I want to put it as a link in the new tab page under "most visited websites"
I then expect to only have to click on the newly created icon to greach my local html file.


Actual results:

I get a 403 error. This is due to firefox automatically adding http:// at the start, before file:///

Original link :
file:///C:/index.html
becomes :
http://file///C:/index.html


Expected results:

I expect my link starting with file:/// to not get http:// added before it.
Problem also occurs with ftp:// protocol and maybe some others.
I don't see a security reason to prevent adding protocols other than http to this page.
