Created attachment 804994 [details] broken tabs User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release) Build ID: 20130803192641 Steps to reproduce: Installed the fxChrome theme on Firefox on Linux Mint 15 with Gnome-Shell. Actual results: The original tabs form is still kept behind the new ones, resulting in a kind-of broken look. Expected results: Old tabs should not be visible.
Does this work on FF 22 ? This looks like an addon (theme) issue, and not a Firefox one. You should send a notification to the theme's developer.
