Firefox title bar is always GRAY in Windows 10!

Just had a clean install of Windows 10... and the title bar in Firefox is now gray! And it doesn't change when the window becomes active. I THOUGHT I followed instructions on how to get the color back in the Firefox title bar. In the Firefox Profile folder, I created a new folder, (and named it "Chrome"). Then I created a new file, <userCrome.css>, inside the "Chrome" folder. The instructions gave some code that goes into the "userChrome.css file. I pasted the code in there and restarted Firefox.... and nothing happened!

Does anybody have any ideas as to what's happening here?

But didn't you read my post? There were instructions on how to get color on the Firefox title bar. The instructions didn't work! I was wondering why. Where did you read that the title bar in Firefox is always gray in W10? Then you can't tell when the window is active or not.

Guess I'm missing something here, the 2 posts read like you are having a discussion/argument with yourself.

The problem you describe also happens with Firefox on Linux Mint. It's the Tabs tabs that change color/shade to show active or inactive.

Same thought I had when I read post #2

I'm guessing you are referring to the Tab Bar, not the Title Bar.

Works for me!

Hi, @Mr Mag00:

In addition to the excellent advice already offered....

Yes, the default theme for Firefox under Win10 uses a light gray background for the UI, including the background for the navigation toolbar, the bookmarks toolbar, the tabs.

There are many, many ways to customize/change that -- some of them are easier than others.
If you want to go the "userchrome" route, you may want to look into the Stylish extension.
(And there is excellent, expert, free help with userchrome modifications at this user community: blog.mozillazine.org)

It might be easier to find an extension HERE that does what you want.
For example, ColorfulTabs will assign different, random colors to each new tab.
Classic Theme Restorer contains many, many options for customization -- it might provide an option that does what you want?

There are also many THEMES for Firefox. Perhaps one of those will do what you want?

Before implementing too many changes to your Firefox profile, you might want to consider backing up your existing profile (or at least critical data, such as bookmarks), and/or creating a new, test profile for experimenting. That way, you will have a way to roll back changes, if needed.

>>Perhaps if you could please provide us with a bit more detail exactly what you want to do, we could provide more specific help.

Thanks!

Great minds think alike.

I don't do a good job here of setting out my embedded links so that they are obvious and readily visible to the reader.
Your way of doing it works better.
Thank you for providing that additional clarity for the OP and for others reading this thread.

Cheers,
