Don't know if deepest sender will still work after this but the author another extension I use had this to say:
Firefox users should note FF43 was released 15th Dec, and this version of Firefox automatically disables any "un-signed" extensions including FBP.
It is possible to enable/re-enable unsigned extensions to be installed in FF43 by changing a Firefox setting: Type about:config into the URL bar in Firefox, then in the Search box type xpinstall.signatures.required then double-click the preference, or right-click and select "Toggle", to set it to false. This will allow you to install or re-enable any unsigned extensions.
