User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170417180824 Steps to reproduce: Enable the Compact Dark theme. Open the menu on the top right: it uses a light theme, including the "customise" part. or Open the bookmarks or history sidebars: everything is in a light theme. or Click on the bookmarks/downloads/developer tools (wrench icon) icon in the extension bar: they also use a dark on light theme. Actual results: Many parts of Firefox use a dark on light theme even when I enable the "compact dark" theme for firefox, including the scrollbar. It kind of makes the whole thing ugly unless you have a dark theme active on your whole system (which leads to many difficulties with reading text a lot of the time). Expected results: I expected the whole Firefox application to be light on dark. For example, if you install the "Blackfox V2" theme from the store, although it may look a bit ugly, the entire application is light on dark. Including all menus and the scrollbar.

The omnibox search suggestions are dark on light as well.

As Aurora is going to be removed, not sure if this bug will stay open.

We're aware of this. There simply hasn't been time for people to invest the (significant) effort to work on this. (In reply to Loic from comment #2) > As Aurora is going to be removed, not sure if this bug will stay open. The themes are now part of release as "compact themes". Devedition will continue to exist even when aurora is removed, as I understand it, though this isn't the best place to discuss it. :-)
