Package: xul-ext-adblock-plus Version: 2.6.6+dfsg-1 With the introduction of firefox-esr in debian jessie, the adblock-plus plugin provided in the debian repositories seems to have lost its user interface. The plugin itself however seems to be working properly. The firefox-menu entries are missing and I did not find a way to configure the plugin using firefox-esr.
Version 2.7.3 appears to not have this issue.
