Hm, last official release was 8 months ago. https://addons.mozilla.org/en-US/firefox/addon/facebook-container/ https://addons.mozilla.org/en-US/firefox/addon/facebook-cont... The github page looks fairly active, and there is a fix merged already for this https://github.com/mozilla/contain-facebook/pull/936 https://github.com/mozilla/contain-facebook/pull/936 and once issue #933 gets merged, it will generate a source release for 2.3.11 at https://github.com/mozilla/contain-facebook/releases https://github.com/mozilla/contain-facebook/releases which will probably become 2.3.12 on AMO after some manual intervention.
