Firefox 4's App Tabs have a feature where an App Tab with new content (e.g., a new mail arrives in Gmail) will cause the tab to "glow" until it is revisited, similar in spirit to badge notifications in Mac OS X and iOS.

Here's what I'm talking about:

Glow on Firefox 4 App Tab

Is there a way to disable this? While it is a nice feature, I keep distractions and interruptions on my desktop to a minimum.

There is no option for this as far as I know, but you can disable or change the color in your userChrome.css.

If you've never done that, locate your Firefox profile, which will be placed dependent on you OS type (see How do I find my profile?).

Change to the chrome directory in it, and edit or create the userChrome.css file to contain these lines:

.tabbrowser-tab[pinned][titlechanged]:not([selected="true"]) {
    background-image: none !important;
}

That should do it until Mozilla changes things.
