Upgraded to Windows 10 & Firefox 47 - now almost impossible to make out active tab

When I went from Windows 7 to 10, and also to Firefox 47, the title bar, scroll bars, and active vs. inactive tab color difference became so slight that it's extremely difficult to see the scroll bar button/spacer compared to the full scroll bar, and almost impossible to make out the active tab. The title bar is also grey, which is irritating. I don't like most "themes" because they typically make it hard to see the toolbar buttons. But it would be nice if I could make just the title bar blue or something instead of light grey.

I found an add on that makes the scroll bar issue bearable - but it seems there ought to be some way to fix all of this, rather than having to use add ons... plus, the biggest problem/irritation now is not being able to see the active tab easily - and I haven't found anything to fix that. I did find some info on "usercontent.css" that showed how to change the active tab font color - but I REALLY want the background color of the entire tab to be noticeably different than the inactive tabs... and I cannot find a "usercontent.css" file on my computer - just example ones in my download folder from when I downloaded a profile manager ages ago.

Please help!! How can I safely & easily make the active tab stand out from the inactive ones? Change the title bar color? Enhance the contrast between the scroll bar and the scroll bar button/controller? Mozila really ought to make these things easily adjustable in the program itself... for that matter, they really ought to make it so we can put all tabs vertically down the left or right side of the page rather than us having to use a not so great add on to accomplish that.

But if someone can just help me fix the active tab problem, I'd be most grateful!

Do you ever follow up on the support threads that you start? Or are we wasting our time when trying to help you?

To be used with Stylish:

or to do it without Stylish, copy this code into a userContent.css file that you create. You'll need to create both the chrome folder and the userContent.css file.

@namespace url("");

@-moz-document url("chrome://browser/content/browser.xul") {
    font-weight: bold !important;

Thanks for the reply. Stylish is getting bad reviews for not working well and slowing down firefox - and I don't want to change website page styles anyhow, just some of the firefox aspects as noted in my original post.

As to the css file, thanks for letting me know I needed to create it - I didn't realize that. However, as I said in my original post, I don't want to change the active tab FONT - I want to change the tab background color either for all background tabs, or for the active tab, so the active tab is still easy to read but ALSO is easy to see versus the inactive tabs.

I'd really appreciate the proper css to change the tab background color for both the active and inactive tabs. Also, when I create the css file, does it need anything in it other than the bit I hope someone can provide me to change the tab colors? e.g., any sort of header or other commands for it to be recognized as a css file?

An aside, I don't know why are are attacking me. In over 10 years of using Firefox as my primary browser, I've posted all of 9 questions here and have read every response - some have been helpful, some not. This is the FIRST time I've posted this question.
