Disable Firefox 77 URL bar effects

[rexone]

This is just one of those things that many of us hate - developers add a new 'feature' that is inexplicable in its purpose but is annoying and cannot be turned off... Firefox has a new URL bar with a stupid, enormous red highlighted box around it apparently just in-case you are too stupid to know where to enter your search text...
Previously this could be disabled via > about:config and then turning to false a number of > browser.url.update settings but V77 has broken that.
Anyone know how to turn it off or is their 'we know best' arrogance going to win & I'll have to retire FF as my browser of choice.
I should add... it's not that the function particularly disrupts my use beyond making me cranky everytime I use it. I just have a big problem with developers adding pointless functions that cannot be optioned off.

I'm using FF 77.0.1 and don't see any red highlighted box, just the usual 1 pixel black outline.

I'm using the same version... It pops-out & looks like this...

Are you using a theme, or is that the default theme? Do you have some accessibility features enabled in OS or in Firefox?

The red comes from the system's accent color. Mine is blue.

No. No themes or accessibility stuff.
That's the annoying thing it does that can't be switched off.

Okay. I'm certainly not alone with this annoying issue.
This reddit fix I found got rid of the expanding URL bar & disabled the suggestions list but my in browser the initial bar is still outlined in red (not black);

1. Open about:config and Accept the Risk and Continue.
2. Paste browser.urlbar.disableExtendForTests and create a new Boolean and leave it True.
3. Paste browser.urlbar.maxRichResults and set the value to 0.
4. Restart browser.
