Solved Visited Links No Longer Change Color

This used to work. For example: on elevenforum.com if I click a thread then go back an see it in the list of topics, it would be changed to a darker shade of gray. Or CTRL+click to open in a new tab, then look back at the previous tab, the link would be a darker shade of gray. Other Forums too, and pretty much all websites.

But suddenly it doesn't anymore! (The only site I can find that it does still work on is Google.com)

- Tested in Firefox, Chrome, and Edge.
- Tested on three different machines so far (two Win11 and one Win10).
- Tried rebooting, no change.

I use Chrome's extension Link Control to handle links in my Microsoft Edge browser. It works everywhere for me except on Amazon.

Mine go from bold to light after visited...

Now that you pointed that out, I can kinda see "bold to light" on this forum, but not other sites... Still have no idea why it suddenly changed behavior.
I ended up installing a Firefox add-on called "Gray Visited Links". Doesn't look exactly like it used to, but it's way better than "bold to light" or nothing at all.
