1525990 - Reload breaks Responsive Design Mode for file:/// URIs (tab goes blank, reload animation plays forever)

Status: RESOLVED DUPLICATE of bug 1525188

(DevTools :: Responsive Design Mode, defect)

Description

[Daniel Holbert [:dholbert]]

STR:

1. View any file URI, e.g. file:/// or perhaps file://c/ if you're on Windows.

2. Change to RDM (Ctrl+Shift+M)

3. Reload (Ctrl+R)

ACTUAL RESULTS:

• The tab goes blank and looks like it's reloading (pays the reload animation in tab-title), but it never makes any progress.
• If you switch tabs away and back, the URLbar is cleared as well.
• These 4 errors appear in my browser console:

Ah, looks like this is already filed as bug 1525188.

Comment 3

Also, for the record: in a fresh profile with mozregression, I actually only see the "Security Error: Content at moz-nullprincipal: [...]" error that I posted in comment 0, when the bug is triggered. The other ones don't appear (not at the time that I reload, at least).
