How to disable blue flash when tab loads in FF 76 for Mac?

Whenever I load a website, there is a brief left-to-right blue streak across the tab when that website loads. I would prefer to not have this, it's not matchy with anything else on my desktop and I find the animation distracting.

It doesn't seem to be connected to any of my add-ons. I'm using the Firefox Light theme. Is this just a theme thing, and I should get a different one? Or is there a way to get this to stop.I checked about:config and past forum discussions and didn't see anything obvious. Thank you!

That is the loading throbber that is shown on a tab when this tab is busy loading the page.
In the past it used to be a rotating PNG image, but in current Firefox releases this is a dot moving left and right.

See this thread for some suggestions about code in userChrome.css.

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

You have made this twitchy nerd very happy. I already had FF set up to enable userChrome.css for other reasons,so this was a quick fix. Thank you!
