When using the Aero theme, the top of my screen (where the tabs are located) have a weird foggy white color. The only parts unaffected by this problem, are the top left and a little of the top right. I don't have High Contrast enabled. I'll attach a picture.

Chosen solution

Note that you're using Firefox 29. It's currently a beta version that will become the stable release at the end of the month.


  1. Install Stylish and restart Firefox when prompted.
  2. Click the ≡ Menu Button and choose Add-ons.
  3. In the Add-ons Manager, click the User Styles category on the left.
  4. Click the Write New Style button at the top. Paste the following in the text box, give the style a name, then click the Save button.
    • You can adjust the opacity value from 0 to 1.
    • This is the Australis Tab Defogger style. I just changed ::before to ::after because it doesn't work otherwise.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#TabsToolbar:not(:-moz-lwtheme)::after {
  opacity: 0.1 !important;
}

tab[selected="true"] {
  color: black !important;
  text-shadow: none !important;
}

tab {
  color: white !important;
  text-shadow:0 0 1px #333, 0 0 1px #333, 0 0 1px #333, 0 0 1px #333, 0 0 1px #333, 0 0 1px #333, 0 0 3px #000 !important;
}

#main-window .tabs-newtab-button,
#main-window #TabsToolbar #new-tab-button > .toolbarbutton-icon {
  list-style-image: url("chrome://browser/skin/tabbrowser/newtab-inverted.png") !important;
}

#main-window #alltabs-button[type="menu"],
#main-window .toolbarbutton-1 .dropmarker-icon {
  list-style-image: url("chrome://browser/skin/toolbarbutton-dropdown-arrow-inverted.png") !important;
}

#main-window #tabview-button {
  list-style-image: url("chrome://browser/skin/tabview/tabview-inverted.png") !important;
}
