User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150402191859

Steps to reproduce:

Open FireFox and open a few tabs
Put computer to sleep
Resume computer from sleep


Actual results:

The top tabs bar within FireFox is "broken" - when maximized it appears translucent (see attached picture) and the close/minimize/maximize buttons are not there and do not function when the area they should be is clicked.

When FireFox is not maximized the entire tab bar appears as a black bar (https://i.imgur.com/TDZUdin.png)


Expected results:

It should function like normal after resuming from sleep.

Oh, I have a 4K screen. This sometimes causes weird issues like this in programs.

Hi Tom,

I have tested your issue on  latest Firefox release (43.0) and latest Nightly (46.0a1) and could not reproduce it. After resuming from sleep the tab bar was correctly displayed and I tested on a 4K monitor too (Dell P2415Q). 

Firefox: 46.0a1, Build ID:   20151216030229, User Agent :Mozilla/5.0 (Windows NT 6.3; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0

Can you please test this on the latest Firefox release (43.0) or latest Nightly (46.0a1, https://nightly.mozilla.org/) and tell me if this still reproduces for you ? When doing this please use a new fresh Firefox profile, maybe also in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). Sometimes this kind of issues could appear when using custom settings, themes or some addons. 

Thanks,
Cosmin.

Considering the fact that the reporter did not provided more information on my request, I will mark this issue as resolved - incomplete. 
If you can still reproduce this, feel free to reopen it and provide the requested information.

Thanks,
Cosmin.
