Want Privacy & cookies (not General) to appear first when opening Preferences, but settings in About:config to do this have disappeared in Ffox 44. Help!

more options

Back in the days of Firefox 37 or so I changed Preferences so that Privacy would show up first, going back to my previous version using "about:config" and setting "browser.preferences.incontent" to "false." This no longer works (and reads false now.) I no longer see settings in "about:config" for browser.preferences.privacy.selectedTabIndex or browser.preferences.lastpanel. WOuld appreciate any help on this. Thanks.

Chosen solution

The browser.preferences.inContent is no longer supported in Firefox 42 and later (bug 1140495), so it is not possible to open a standalone window by setting this pref to false.

You can possibly create a bookmark on the Bookmarks Toolbar with the location set to about:preferences#privacy if you want to open Preferences with the Privacy tab selected.


You can look at the Classic Theme Restorer extension to open Options/Preferences in a standalone window.

Look at the setting(s) in the CTR Options/Preferences here:

  • Options page / window

Let's hear it for bug # 1140495!

I've put the suggested bookmark on the toolbar. By control-clicking I can open Preferences in a new window and then another click gets me to cookies, which I have a thing about dumping every time I leave a site. So this works, but not as quickly as the old version that took me right to Cookies. But still a click shorter than without the bookmark.

Thank you.

Or you could paste this URL into a tab, press Enter to load it, and then bookmark it:

chrome://browser/content/preferences/cookies.xul

Not as pretty as the newer version, but saves a step.

I just realized (duh) that by not closing the Preferences tab created by Cor-el's solution after I've used it, that a single click gets me back to Preferences where I can dump the Cookies. So...a perfect solution!
