good, but Rated 3 out of 5 stars

works well, but I miss some functions from old Auto Context extension. for example, important to me, "Selected Context Menu" in setting = SelectionSK Context / Firefox Context. Many extension adds custom items into firefox context menu and here all are missing :(

This review is for a previous version of the add-on (0.4.1). 

1. if it works well it should get 5 stars, not 3
2. if you miss some functions from AutoContext than would suggest to continue to use AutoContext, it is nice addon
3. starting from version 0.5 SelectionSK provides an ability to integrate with other extensions, feel free to download and test latest beta from the support site
