 Replying to [ticket:27268 rzb]:

 Thank you for finding these, rzb!

 Here is my patch for review: https://github.com/arthuredelstein/tor-
 browser/commit/27268

 > pref("plugins.hide_infobar_for_missing_plugin", true);
 >  - dead pref? hxxps://dxr.mozilla.org/mozilla-
 esr60/search?q=hide_infobar_for_missing_plugin -> 0 results found
 >
 > pref("plugins.hideMissingPluginsNotification", true);
 >  - dead pref? hxxps://dxr.mozilla.org/mozilla-
 esr60/search?q=hideMissingPluginsNotification -> 0 results found

 Yes, I confirmed that "plugins.hideMissingPluginsNotification" and
 "plugins.notifyMissingFlash" were removed in https://bugzil.la/836415. And
 "plugins.hide_infobar_for_missing_plugin" was migrated to
 "plugins.hide_infobar_for_blocked_plugin" in https://bugzil.la/870112 and
 then removed in https://bugzil.la/1027049

 The plugin finder service was removed, so these notifications no longer
 happen.

 > pref("plugin.expose_full_path", false);
 >  - dead pref? hxxps://dxr.mozilla.org/mozilla-
 esr60/search?q=expose_full_path -> 0 results found

 Removed in https://bugzil.la/883671

 The code now uses the "false" behavior always. (It never exposes a full
 path.)

 > unless you have custom code that re-implements this I don't think the
 pref does anything anymore:
 > pref("dom.mozTCPSocket.enabled", false);
 >  - hxxps://dxr.mozilla.org/mozilla-esr60/search?q=mozTCPSocket

 Yes, this pref was removed in https://bugzil.la/1286530. I confirmed that
 navigator.mozTCPSocket is only exposed in chrome contexts.

 > pref("browser.usedOnWindows10", true);
 >  - dead pref? hxxps://hg.mozilla.org/mozilla-central/rev/5dd17564f294 ->
 also uplifted to FF50
 >  - hxxps://dxr.mozilla.org/mozilla-esr60/search?q=usedOnWindows10 -> 2
 remnants for .introURL but nothing for "browser.usedOnWindows10"

 Yes, this was removed in https://bugzil.la/1274633

 > pref("browser.selfsupport.enabled", false);
 > pref("browser.selfsupport.url", "");
 >  - both removed in FF55 -> https://bugzilla.mozilla.org/1361578
 >  - hxxps://dxr.mozilla.org/mozilla-esr60/search?q=browser.selfsupport ->
 0 results
 >  - hxxps://dxr.mozilla.org/mozilla-esr60/search?q=selfsupport -> 8
 results but nothing that looks related to these 2 prefs

 Confirmed.

 > pref("browser.newtabpage.directory.ping", "data:text/plain,");
 >  - dead pref? removed in FF55: https://bugzilla.mozilla.org/1241390

 Confirmed.

 > pref("browser.newtabpage.directory.source", "data:text/plain,");
 > pref("browser.newtabpage.enhanced", false);
 > pref("browser.newtabpage.introShown", true);
 >  - all 3 were removed in FF60:
 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1370930,1433133

 Confirmed.

 > pref("browser.newtabpage.remote", false);
 >  - last remnants removed in FF60 (https://bugzilla.mozilla.org/1355166)

 Confirmed.
