Here is the new style bookmark that works for me:

javascript:location.href='org-protocol://capture?url='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title)+'&body='+encodeURIComponent(window.getSelection())

I also placed the following in ~/.local/share/applications/emacsclient.desktop:

--8<---------------cut here---------------start------------->8---
[Desktop Entry]
Name=Emacs Client
Exec=emacsclient %u
Icon=emacs-icon
Type=Application
Terminal=false
MimeType=x-scheme-handler/org-protocol;
--8<---------------cut here---------------end--------------->8---

Since you are not using a desktop environment, you might also need to
make sure that the appropriate xdg tools are installed. On arch linux
the package is xdg-utils.

I'd recommend copying and pasting the javascript line above into the
location bar to confirm whether it works. If it does, you can then
easily add it to your bookmarks.

Note: There is a bug in the implementation of the new org-protocol url
processing that can lead to multiple "greedy protocol" warnings. (I
posted a bug report about this a week or so ago.)

Hope this helps.
