Firefox 57 on Windows 10 64bit virtual machine

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.

 

@alxg: Yes, we removed the profile (%appdata%\Mozilla\Firefox\Profiles) before installing FF57.

 

Dr.U, could you please try to run FF57 and after that send me the technical report using Help menu of Parallels Desktop? Write the number here. Thank you. I'd like to see the difference between you and mine setup.

 

@alexg, we have sent the report (ID 226982035)

 

I have the same problems since I have installed FF57 ...

 

Hi,
Same problem here.

I can confirm the effect of the settings ThomasB16 mentioned. It works exactly the same way on our W10 pro 32bit VM. Thanks a lot for helping! Really fine research.

 

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.

 

And, after @alexg's defensive rant against my earlier post describing the lack of technical expertise, support and QA for PD ("Hey, it works on _my_ machine; therefore we QA'ed it!), it turns out that, once again, it's Parallel's long-suffering users who have come up with a work around.

 

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'm also running firefox quantum 59.0.2 but in my case the firefox window comes up with no borders and it looks weird. None of the options for the 3D acceleration (None, DirectX 9 and DirectX 10) fixes it.

 

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").
