70.0 menu bar background color now stuck white

more options

since ver 70.0 64bit upgrade, no matter what theme i use (currently 'Complete Black Theme for Firefox', also use 'dark theme') the menu bar background color is WHITE. if i go and swap between themes it turns BLACK/DARK GREY like i want it but as soon as i do ANYTHING it flashes back to WHITE. THIS SUCKS!. never had a problem before. ever! don't give me advice on saying it's W10 theme issue or anything like that - everything was fine until VER 70.0 update was done

If you want to change the background of the tabs, you can install either a theme or a complete theme.

If you want to change the default page background color,

   1.Click the ≡ Menu Button and choose Options.
   2.Click the Content icon.
   3.Click the Colors button.
   4.Next to Background, click the swatch and pick a color.

nope, NONE of this works. as i said, i can change the theme and when i ENABLE it the menubar background goes BLACK - just what i wanted. all i have to do is MINIMIZE then UN-MINIMIZE and the menubar background is WHITE. that fast. ANY new WINDOW or NEW TAB and the menubar background is WHITE. LOOK AT THE PICS I ATTACHED
