Chrome dev tools settings: where is the Experiments tab to Allow custom UI themes?

Question

I am using chrome version 36+

according to this page, I should be able to allow custom themes using the following instructions:

Installation Instructions

• Add this theme
• Goto chrome://flags and Enable Developer Tools experiments.
• Open developer tools settings, select Experiments tab, and check 'Allow custom UI themes'.
• Reload devtools.

I do not see such a tab in the dev tools settings. I see only 'general', 'workspace', and 'shortcuts'

Answer 1

These are some simple steps to follow, hope it will be helpful.

1. Open a new chrome tab, type chrome://flags
   
2. Find, "Enable Developer Tools experiments." using ctrl/cmd+f or simply searching for it by scrolling down the page.
   
3. Click the "enable" link
   
4. Click on "Relaunch Now" at the bottom of the page.
   
5. After restarting Chrome, open DevTools, DevTools settings, and select the experiments tab.
   

Now select the experiment you want (e.g. "Allow custom UI themes").

You need to reload devtools after: Alt-R will reload devtools itself, or you can just close and reopen it.

Answer 2

To get to the Dev Tools Experiments area you have to click on the gear icon in the inspector.

If still not working you should go to:

chrome://extensions/

And click the 'Enable' checkbox for the DevTools extension you wish to enable.

Answer 7

loislo's answer is absolutely right (You need to restart the browser after changing the flag at chrome://flags). But notice that your chrome can work in the background. Go to the tray, look for the chrome icon and exit.
