Hi all, in bug 1465061[1] I intend to remove the stand-alone options window so that preferences will be shown and edited in a tab like Firefox has done for years. These are the reasons: * "Preferences in tab" exist in Thunderbird since TB 37 hidden behind a preference (mail.preferences.inContent). Removing the legacy stand-alone window will reduce the maintenance burden. * Mozilla core support for preferences is geared towards Firefox' preferences in a tab, so it will become increasingly difficult to support the legacy panel. For example we had to adopt the preferences.xml bindings into comm-central. * Mozilla core has moved to using the 'Preferences' object (supplied in toolkit/content/preferencesBindings.js) and the C-C's preferences code has significantly diverged from M-C's which makes it very hard to follow M-C. Most recently we noticed that in bug 1460721[2] where a simple port of M-C changes obliterated the stand-alone window. * Thunderbird should be modernised and follow Firefox with regards to preference editing in-situ. * This will open the path to the Account Manager in a tab, bug 1096006[3]. Any objections? Speak up now or forever hold your peace. Jörg.

Instead of using Alt+key you have to use Alt+Shift+key and tabbing and entering is a bit different. All in all not enough reason to block removing this though… Onno
