I test 110 revision and sync don't work with it too.
GuillermoMolina, I try to add post on your site at http://www.guillermomolina.com.ar/index.php/en/projects/firefox-kwallet-extension/forum-topics but can't do this.
I fill all fields, enter the captcha and do submit, but got the error:
NO SUCH POST
Also sending messages via contact form on site seems don't work too... And I can't register on your site as new user :(
I think the error is in Joomla module settings, I can help you with this too, because I am the site developer on Drupal and Joomla :)
Try version 0.10 from my web page: http://www.guillermomolina.com.ar/index.php/es/archivos/doc_download/29-firefox-kwallet-extension-version-010
