I have not had a change to test this on older Ubuntus with the new nightly firefox yet but I can confirm this is a issue with 15.04 & 15.10 . And since when this hits in the latest firefox (that will be shipped on nearly all supported Ubuntu builds) this fix may need to be tested and applied to older and newer builds of Ambaince Themes (EG one in 14.04 , 12.04 etc.) I am not sure yet however.

They're missing a "background-color" for the .tooltip {...} CSS rule in their config files. They have a "tooltip_bg_color" variable, which they use to set up a background-image (really a gradient), but there's no background-color. This causes problems for GTK3-enabled Firefox, because it reads back some system-colors by setting up a dummy tooltip and reading the (currently-not-useful) background-color and the foreground-color. Right now, this produces unreadable output (for the user) with white-text-on-a-white-background, as shown in this screenshot: https://bug1187203.bmoattachments.org/attachment.cgi?id=8638351 The solution is simple -- just add this one line to the ".tooltip" CSS rule in gtk-widgets.css: background-color: @tooltip_bg_color; For more details, see bug https://bugzilla.mozilla.org/show_bug.cgi?id=1187203 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: light-themes 14.04+15.04.20150410-0ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-23.24-generic 3.19.8-ckt2 Uname: Linux 3.19.0-23-generic x86_64 ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 CurrentDesktop: GNOME Date: Fri Jul 24 17:35:25 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2015-05-18 (67 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) PackageArchitecture: all SourcePackage: ubuntu-themes UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1478173/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
