So, whenever I click a link that will open in a new tab, the whole firefox background will flash in bright white color for a second until the page is loading. How can I change this background color?

The above style rule covers the time before Firefox starts painting the default page background color (or the page's own background color). To soften that a bit you could change the default page background from pure white to light gray:

(0) Select and copy the following color value:

#F8F8F8

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste color and pause while the list is filtered

(3) Double-click the browser.display.background_color preference, delete the existing value, and paste the value for light gray

This color will show on pages that do not specify a background color, such as

It's simplest to use an add-on or custom style rule.

For example, I use this rule, which replaces the white background behind the page with a slate bluegray color:

@-moz-document url(chrome://browser/content/browser.xul) {
  browser[type="content-primary"] {background: #778899 !important}
}

To install that rule (or another custom style rule) into Firefox, you can use either:

Found the bug, I had "use system color" ticked in the firefox color settings... disabled, now working as expected! :D (And following your steps!)
