I recently switched from Linux to Mac OS X, and one little tweak that didn't survive is disabling the blue highlight "glow" that Firefox adds to App Tabs when they have updates. Any idea how to do that?
I followed these instructions to disable it on Linux, but they don't work on Mac OS X. I have this in my ~/Library/Application Support/Firefox/Profiles/personal/chrome/userChrome.css
file:
.tabbrowser-tab[pinned][titlechanged]:not([selected="true"]) {
background-image: none !important;
background: none !important;
}
...but no luck. Putting other CSS rules in that file does work though.
I'm on Firefox 19.0 on Mountain Lion (10.8.2).
