Please explain the problem in detail. What happens? What is/are the exact error message(s) ?

Are these something you want but no content? How/when do they show up?

After the last update all the tabs are now black except the active one. Am I the only one who noticed this? This is very distracting visually, and now you have to adjust to the reversed (white text on black) appearance every time you look for the right tab you want. When these tabs are black, they fight for your attention more the than the active one. This makes no sense, and it often obscures the logo on the tab. Why do they change things that were not broken? How do I get them back to gray like they are in all other programs?

This is the first we heard of this.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thanks for your quick reply. Unfortunately this did not solve the problem, it does the same thing in safe mode. BTW if it matters I am running Windows 7 on this computer, I have not upgraded Firefox to v.83 on my tablet or laptop yet because I did not want this on either of those and I rarely use them. This is not a functional problem but I just don't like the look of it this way. If you have any other solutions please let me know - hard to believe I am the only one with this issue. Thanks again!

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

In Safe Mode, the problem does not appear. The appearance is as normal with only the standard VGA working with default color scheme, so I guess the problem has to do with my video card settings? Just a guess!

If there is no problem in Windows Safe Mode, the issue is with something else on your system.

See if there are updates for your graphics drivers https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

As a test, disable your protection programs.

Ok, so I solved the problem, thanks to your help. I wrote an explanation for you that disappeared when I clicked 'Solved the Problem' above before I clicked Post Reply below. So to put it quickly again: I dug more into Options and Menus thinking it had to be within Firefox not my graphics card or drivers since this only showed up here. I found Extensions & Themes in the Options which I had never seen before. I thought this had to do with Extensions and Add-ons which I had used before. When I checked it out I found that somehow the Dark Theme was enabled at the same time that I updated to v.83.0. I don't think I did this, I didn't know there were different themes and I don't even like it when my phone goes to dark mode at night. Hope this is not repeating what I wrote before. Thanks again for your help, I have always gotten good support and that's why I still use Firefox. I just wanted to let you know, hope it helps.

That was very good work. Well Done. Please flag your last post as Solved Problem as this can help others with similar problems.
