User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171113102334

Steps to reproduce:

From Firefox 57 (no problem before), it is no more possible to have a site listed in the "Top Sites" section of the welcome screen (start page of firefox) whose URL is a local file (file:///xxx).

- Welcome screen -> Top Sites -> Edit -> Add
- Fill in "Type or paste a URL" -> e.g. "file:///C:/test.html"
- Click "Add"
(see screenshot)


Actual results:

Click in the Top Site icon just added -> nothing happens.
If I Edit the link, firefox has changed the URL:
- from : file:///C:/test.html
- to     : http://file:///c:/test.html    ("http://" INCORRECTLY ADDED)

Note 1) that if I type directly the address "file:///C:/test.html" in the address bar, it works (of course !)

Note 2) the links in Top Sites (with URL=file://xxx) that were already present in Firefox 46 do not work any more: same symptom: click in the Top Site icon -> nothing happens (but if I edit it, the URL is still "file:///xxx" without the "http://" added)


Expected results:

Click in the Top Site icon just added -> firefox should open the site
