hello frodin, i suppose this won't work anymore since per-window private browsing mode was introduced in firefox 20 and this documentation is outdated.

Try the -private-window command line switch if it is no longer possible toggle it.

The Firefox release source code still shows a reference to -private-toggle, but the source code of the current 21.0 beta and later no longer gives results.

yes... but using:

firefox-path.exe -private-window url1 url2

opens a private window and a normal window with url1 and url2. This is a design fault as the args in command line say something else.

With -private-toggle we can setup how the firefox will open not wasting clicks/copy-pastes/bookmarks (even for a folder with multi-bookmarks there is no functionality to add a shortcut for a quick way to access our links)

Also might be similar to that https://bugzilla.mozilla.org/show_bug.cgi?id=829180

There must be an option (even to config) to open everything in private mode if we wish.

Thanks

PS. also something else: why only "new private window"... if you want to do it like this you must add and "new window" option.

Just use the -private switch.
