1296314 - [Firefox 48.0] browser.tabs.drawInTitlebar not working on Linux

Status: RESOLVED DUPLICATE of bug 513159

(Firefox :: Theme, defect)

Description

[xfce0]

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160729072959

Steps to reproduce:

Hi,

Here are my steps to reproduce:

- I have Fedora 24, 64 bit with 2 desktops: Gnome and Xfce.
- Install Firefox 48.0.
- Open about:config and change browser.tabs.drawInTitlebar to true (default is false).
- Restart Firefox.


Actual results:

- Tabs are not drawn in title bar.

I thought it could be because of some of my extensions. So I tried with --safe-mode. But nothing changed.


Expected results:

Tabs should be drawn in title bar.

Thanks for your hard work.

That's OK, it is much better to have a duplicate bug on file than it is for a bug to go unreported. Thanks for your help :)
