In Firefox 3.6.x, I was able to change the text color to red in the URL bar when in private browsing mode by adding the following in the chrome folder, overly.css file for an extension:

[browsingmode=private] #urlbar { background: #000  !important; color: #F00 !important; }

That code no longer works for the same extension in Firefox 4.

Any suggestions as to how to change Firefox 4 URL text color to red when in private browsing mode?

Got it! Thanks

I used light yellow background with red text:

[privatebrowsingmode="temporary"] #urlbar { background: #FFFFCC  !important; color: #F00 !important; }

Is there a reference for the Firefox 4 "css descriptors" changes, for example:

[browsingmode=private] is now

  • [privatebrowsingmode="temporary"] or
  • [privatebrowsingmode="permanent"]

with some explanations?
