I'm working on a Windows 7 system where the preferred browser is Firefox.
When Firefox opens, the screen controls (Minimize, Restore Down/Maximize,Close) in the upper right corner are completely blacked out. There is nothing but a black rectangle where all 3 buttons normally are.
The buttons are "there" and work but can't be seen - so one has to guess on their location to use them.
My job is to fix Firefox so this doesn't happen.
I've read a lot about this and most of the instructions point to doing things with Firefox.
I've done those things and even uninstalled Firefox and reinstalled it with no help.
I've seen such things happen with Internet Explorer that had to do with Windows themes.
So, I set the theme to a very simple one. Still no help.
I've accessed this computer with GoToAssist Express (which tweaks the display scheme to support the remote connection) and, in this situation, *the problem goes away*!
So, I'm going to have to go on site to deal with this.
I'm wondering what suggestions there might be to deal with it further?
I strongly suspect this is a Windows settings issue.
