Yes this was added in version 2.6.13. In the next version (2.6.14) the default shortcut will be removed. But it's still possible to define a shortcut. Each user can now and in the future define the shortcuts themselves, see here: https://support.mozilla.org/en-US/kb/manage-extension-shortcuts-firefox
