Auto-sync about:config settings #


For each setting to be synched, add:

services.sync.prefs.<setting> true



Enable media keys on MacOS #


In about:config:

media.hardwaremediakeys.enabled = true

// For syncing the setting = true = true

// For syncing the setting = true

Restore Pinned Tabs on Demand #

Note sure how to prevent the pinned tabs from opening at all, but at least this delays them loading, until you activate the tabs:

browser.sessionstore.restore_pinned_tabs_on_demand = true

services.sync.prefs.browser.sessionstore.restore_pinned_tabs_on_demand = true

Hide Native Tabs (for Tree Style Tabs) #

In about:config set:

toolkit.legacyUserProfileCustomizations.stylesheets = true

// For syncing the setting
services.sync.prefs.toolkit.legacyUserProfileCustomizations.stylesheets = true

Then in the <Profile folder>/chrome/userChrome.css:

/* hides the native tabs */
#TabsToolbar {
  visibility: collapse;

#sidebar-header {
  visibility: collapse !important;
