User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20151216175450 Steps to reproduce: I have the following code in my userChrome.css: ### /* Make secure Web site URLs stand out */ #urlbar > .autocomplete-textbox-container { background-color: #FFf0f0 !important; } #urlbar[level="low"] > .autocomplete-textbox-container, #urlbar[level="high"] > .autocomplete-textbox-container { background-color: rgb(245,246,190) !important; color: black !important; } #urlbar[level="broken"] > .autocomplete-textbox-container { background-color: #FFEEEE !important; } ### Actual results: .autocomplete-textbox-container always has #FFf0f0 color, even for secure sites. 'level' does not work in selectors. Expected results: HTTPS sites without mixed content should have rgb(245,246,190) color in the .autocomplete-textbox-container. The code stopped work after update from 43 to 43.0.1.

Paolo, is there an alternative for 'level'?

(In reply to Jorge Villalobos [:jorgev] from comment #2) > Paolo, is there an alternative for 'level'? We now set the "verifiedIdentity" and "chromeUI" classes on the "identity-box" element: http://mxr.mozilla.org/mozilla-central/source/browser/themes/shared/identity-block/identity-block.inc.css#50 It may be possible to style the rest of the URL bar based on these classes, using the sibling selector "+".

Closing this bug as the change was intended and there are alternatives available.

Author of the Firefox 2 theme here. (ID: 6898) verifiedIdentity has existed on the identity block for ages. The point is, you cannot style the background of the url bar anymore depending on security level (level low/high/broken) due to the attribute being removed (bug 1204486) #urlbar[level="high"][pageproxystate="valid"] > .autocomplete-textbox-container #urlbar[level="low"][pageproxystate="valid"] > .autocomplete-textbox-container http://mxr.mozilla.org/firefox2/source/themes/classic/navigator/navigator.css#198 (committed Jul 2006!) #urlbar[pageproxystate="valid"] > #identity-box.verifiedIdentity ~ .urlbar-input-box I've tried using .urlbar-input-box with verifiedIdentiy/verifiedDomain (and some margin fixes), but since .urlbar-input-box seems to be anonymous, the line above doesn't to work. Is there a way to achieve this now that the level attribute is gone?

I confirm it, apparently the sibling selector doesn't work here since the latter element is part of the anonymous content of the textbox binding. Dão, is there any other way to achieve this with the current URL bar structure? Or maybe we should move the new identity block styling classes to the URL bar textbox and update our CSS rules accordingly?

I don't think we should do that. Changing the background color of the entire location bar has been discouraged ever since the identity block was introduced, which we think is a superior UI with less room for misunderstandings.
