This had been working great for me until very recently. I am logged into Google but no bookmarks show when I click the Fess toolbar button. Help! I've tried clicking LOGOUT and then logging back in as well as uninstalling/re-installing the addon. No luck yet =(This review is for a previous version of the add-on (0.1.7.1-signed).
Look messages in the console (Ctrl+Shift+J): GBE:xxxxxxx.Try to install version 0.1.9 - https://addons.mozilla.org/ru/firefox/addon/fess-google-bookmark-extens/versions/
