It appears that with my update to Firefox 44 a few days ago, the bookmarks toolbar has gained the same opacity as the URL toolbar (adding something like 50% of a gray tone).
I have tried
- reinstalling the Aurora Australis theme already, to no avail.
- the "Open Menu" -> "Customize..." dialog, but I can't seem to find a knob to frob the bookmark toolbar opacity.
How can I get rid of the opacity so that the theme is completely visible? I'm willing to hand-tune any
userChrome.css you name in the absence of an easier method.
