CSS code to force "about:preferences" to open in a separate window?

Posted

Hello,

What is the CSS Code to force the "about:preferences" menu to open in a separate window?

This used to be possible using the "classic theme restorer" extension but it's since been depricated with version 57+.


Thanks in advance.

This does not solve the problem as the window is not accessible from clicking the "open options" button next to the URL bar.

You used to be able to use the following boolean set to true:

browser.preferences.useOldOrganization

but it appears that's also been removed and when manually adding it has no effect.

You would normally use this command to open the about:profiles page: openPreferences() You can try this command in the Browser Console. I'm not aware of a way to open the about:profiles page in a standalone window apart from using A bookmark and Shift plus left-click this bookmark or tear off a tab with this page (Move to New Window).

It's unfortunate that the devs thought it was a wise idea to remove this functionality. Now you are unable to navigate back to the page you were on prior to entering the "about:preferences" menu if you use the "open options" button to get there.

Pretty large oversight.
