Hey, I can relate to your frustration. After getting some very poor tech support (whereby new dudes would ask me to do what previous dudes had asked me to do already) I got really annoyed and emailed Parallels management to complain. They put level 2 guys on my case straight away and I am still dealing with them. Maybe email and complain about the level 1 support. Something really needs to improve in that department. I worked in Helpdesk management for years, and If any of my staff were performing that poorly, they would have been fired.

I have the same problems since I have installed FF57 ...
I was also experiencing the same FF57 startup flashing window problem on a Parallels Windows 10 Pro 64bit VM on a Mac Mini late 2012 with MacOS Sierra latest version but not on my Windows 7 or 8.1 VMs.
I then created a new VM with a fresh Windows 10 install and a FF57 install and FF57 worked correctly. I then started to do my usual Windows 10 custom settings all at once and then FF57 started having the same startup flashing problem. Luckily I had taken a snapshot of the fresh install before customization that worked so I went back to that and then made each of my customization changes one at a time testing FF57 after each change.
For me, I was able to identify that under Settings|Personalization|Colors if I had both a "Windows Colors" selected and show accent color in "Title Bar" selected it would produce the flashing windows on FF57 startup. If I either let "Windows automatically select an accent color" or unchecked the show accent color in "Title Bar" then it would correct the problem and FF57 ran correctly. If I then went back and reselected those two options FF57 would exhibit the startup flashing window problem.
With further testing if I let "Windows automatically select an accent color" and left the show accent color in "Title Bar" selected and FF57 started correctly then I could close FF57 and then choose my own "Windows Color" again and FF57 would startup correctly until then next reboot and then FF57 would go back to the flashing window at startup again. I could once again correct the problem by making either one of the changes that I indicated above. I was able to reproduce this behavior multiple times.
I then went back to my original Windows 10 VM that I first found the FF57 startup flashing windows problem and unchecked the show accent color in "Title Bars" and FF57 started up correctly.
I hope this helps others and allows Parallels to reproduce the problem so they can find a solution.

I found a way to easy fix the problem (thanks again to ThomasB16).
1 Settings|Personalization|Colors ->unchecked the show accent color in "Title Bar"
2 Restart FF, it should work now.
3 In FF, Click the menu button
and choose
Customize....
4 In Themes change the Theme from "default" to any other and restart FF
5 Settings|Personalization|Colors ->checked the show accent color in "Title Bar"
That's it!

I can confirm that changing the Theme to anything except "default" works. Change it before you do the upgrade to 57.x and everything works. If you change it back to "default" after installing 57 you'll have the flashing problem again with no easy way to fix it except to roll back to a prior snapshot.
Sorry for the confusion. "Settings->Personalization->Colors" are the settings in W10, not in FF! (https://support.microsoft.com/en-us...-10-change-your-desktop-background-and-colors). You can change this settings after the installation of FF57. So you don't have to go back to FF56.
You are the man, ThomasB16 ! Great research and very clear post. THANK YOU SO MUCH !!!

Thanks to ThomasB16, I checked the Personalize and Colors panels, and fixed it by that setting an automated highlight color based on the background. I could then select a custom color again without the glitch reoccuring anymore.
Hello...I was having this same issue with my MacBook Pro (mid-2015) running Parallels Desktop 13 Pro, Windows 10 (version 1709), and Firefox Quantum (X64; version 59.0.2) for several days now. However, last night I changed the Graphics setting under the "Windows 10 Configuration" to Advance Settings/3D acceleration: DirectX 9. I also put a check mark on "Automatic graphics switching". Changing the setting to "DirectX 9" appeared to fix the issue with flickering in Firefox Quantum and the black search field and the address bar for me. Not sure if checking "Automatic graphics switching" was necessary. Hope this helps others.

That works for me. If i switch back to DirectX 10 then the issue is back. Switch to DirectX 9 and all works as it should.

I had something, perhaps, similar. Black space in a window with whatever version of Firefox Quantum I tried. The solution was to turn off Hardware Acceleration in Firefox. Does that suggest a video driver issue? Windows 10 with Firefox 61.0.1 64 bit. I also had black tabs, but going to the Light Theme fixed most problems except the black space in some apps. Turn off Hardware Acceleration (Options/General/Performance, turn off "Use recommended performance settings" then uncheck "Use hardware acceleration when available").
