this is by far the best scrapbook alternatives in the post firefox 57 world, I understand many negative reviews are probably due to the extra steps needed after installation: you need to go to Add-ons Manager, click the ... to go to the settings\install and follow the instructions to download ScrapBee backend executable then install that on your local machine, before the ScrapBee button even shows up on the toolbar!! and also it is a little bit inconvenient to have the sidebar open all the time if you want to do "Capture Page" instead of "Capture Advanced...", but this is well developed add-on and the inconvenience is caused by Firefox's new architecture, and the workaround deployed by this Add-on is well worth it, you know it because you are aware of the usefulness of the original Scrapbook plugin, that is the reason you are looking for an alternative in the first place!! So suck it up and thank the Author!!
