Tab-bar Buttons are white, and invisible in Windows7

New Firefox Quantum has introduced new design and new UI bugs.

While the bug with disappearing text is sporadic and font-scaling related, there is a PERSISTENT UI BUG, now traveling from version to version. Its name is:

"Invisible TAB-bar buttons"

Buttons are simply WHITE on WHITE background. These are tab-scroll arrows, tab"+", and tab-list buttons, by default.

It happens on EVERY WIndows7-based PC with EVERY Firefox installation in default configuration (no tweaks, no themes).

I wonder, how the developers should hate Windows7, which is still installed on more than 30% of Win-PCs worldwide.

Hi, there is no design changes. You are having issues with the program itself

It happens on EVERY WIndows7-based PC with EVERY Firefox installation in default configuration (no tweaks, no themes).

Fortunately the above is untrue as to all Firefox Installs everywhere.

Separate Security Issue, please update your : Flash 22.0 r0 By using this https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html As the above is so old. Flash Player Version: 29.0.0.171 Current Version https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, . . . .) Note: Other software is offered in the download. <Windows Only>

Please do this : In your Windows Search Bar in the Start type CMD.exe and Right Click it to Run as Administrator From the Command Prompt type or Copy/Paste Sfc /scannow ( Sfc<space>/scannow ) then Enter. When it is finished please reboot.

Then please do this : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 60.0.1 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.
