Blank login screen on Firefox?

[nealc 0]

My copy of Emby (3.0.5785 on Ubuntu 12.04) now gives (on FF 43.04) a blank grey login screen.

 

I can log in using IE 11.096, but for FF the opening page appears to be a lot of commented-out <div>s - the background of the login page, no buttons etc.

 

FF web console has some JavaScript errors on load:

unreachable code after return statement site.js:7:7
SecurityError: The operation is insecure. store.js:51:0
ReferenceError: appStorage is not defined site.js:165:5

 

I've tried restarting both client & server - and swearing a bit  - without making any difference. Any more erudite ideas gratefully received.

Try clearing browsing data. I can't reproduce it.

Found it!

 

If i set Firefox to ask before accepting cookies, emby login screen doesn't load. (Options, Privacy, Keep until: Ask me every time)

Choosing Keep until: they expire or Keep until: I close Firefox  both work

Not accepting cookies also fails.

 

Although I can't see any cookies set by my server...? Odd.

Yea we don't use cookies. But maybe it put the browser into some kind of private mode.
