And much more...

In the main entry, type:

• about:plugins : to get a list of loaded plugins
• about:bookmarks : to open bookmarks tab
• about:history : to open history tab
• about:cookies : to open cookies manager tab
• about:settings : to open settings tab

Actually, supported languages are 5:

• German (de_DE)
• English (en_US)
• Spanish (es_ES)
• French (fr_FR)
• Italian (it_IT)

Any image can become a theme. Right click on any image and click "Apply as theme".

In order to use Poseidon with a proxy, you can try:

Once Tor is started through arm or the discontinued vidalia, you can launch Poseidon in these ways:

$ torsocks(or proxychains) ./poseidon (default mode)

$ torsocks(or proxychains) ./poseidon -i (defcon mode)

If you installed WebKit 2.16.x (or higher) and Poseidon 0.5.5 then you might want to use Proxy Manager. You can find it in the "Utilites" tab or just press its shortcut key "Ctrl+X".

To increase security even more, go to "Settings" > "Miles O'Brien", set "set-enable-java", "set-enable-javascript", "set-enable-plugins", "set-enable-webgl" to "False", save the new settings and re-launch Poseidon in Defcon Mode. It's also a good practice keeping your browser un-maximized during the navigation and set a custom user-agent ("set-user-agent").

Install xdg-utils then execute:

$ xdg-settings set default-web-browser poseidon.desktop
