But on Firefox 4 new Windows Theme, no sign of Private Browsing or Normal browsing in title bar. And there is not Private Browsing displaying in latest Windows Theme Mockups (https://wiki.mozilla.org/Firefox/4.0_Windows_Theme_Mockups). I think that, the user confusion happen if there is no displaying to individuate browsing mode. Reproducible: Always

I noticed this as well. I don't think we should ship Firefox 4 like this.

Arrg, why does bugzilla do that - when I cc'd myself it set it to 'unconfirmed', setting back to "new"

Related to/Dupe of Bug 513418?

I'd say 513418 is a possible fix for this. This is a regression from drawing in the titlebar though, since you used to be able to look at the window title and see "(Private Browsing)".

We could presumably fix this in some other way. Also, that bug is not a regression whereas this one is. As long as we recognize those two facts, I don't really care what happens with this specific bug.

At least blocking final, but we probably want to fix it before hand.

I think a kind of subtle and simple way to do this in the short-term would be to put the mask in the firefox button and change that button to purple in private browsing mode.

As a temporary solution we might add PB icon into tab bar when PB is active.

(In reply to comment #10) > As a temporary solution we might add PB icon into tab bar when PB is active. I think that would be as much work as changing the Firefox-button, so let's get the proper solution in there instead. If I only knew how to create patches and build Firefox with them, then I could do it myself (or at least try).

I was thinking purple button with "Firefox (Private)" the icon might be had to pull off at 16x16. Either way, in addition to the button change we are also hoping to pick up something like bug 513418, although darkening the theme is opportunistic.

(In reply to comment #13) > although darkening the theme is opportunistic I'm finding this mockup very attractive.

I guess this bug should also depend on bug 588655?
