I've been using Pocket for years. Recently (can't tell exactly when) the behavior on my Macmini became different than on my Macbook (as of a few hours ago both were running 48.0.1). On the mini, the icon to save a page disappeared from the URL area. The icon in the toolbar remained, but now all it does is allow me to mark a page, having lost the functionality of showing a drop-down list with controls - VERY helpful). I've tried to remove and reinstall Pocket on the Mini, but the strange thing is that it no longer appears in the extensions list. This is pretty bizarre since it clearly is still loaded since the icon is in the toolbar. Then I remember seeing some news about collaboration between Mozilla nd Getpocket, and thought perhaps this is some new way that the latest and greatest Firefox is SUPPOSED to work (just upgraded to 48.0.2 before writing this note). I also note that I can no longer find Pocket in the list of extensions available for download.
