Is ESB Window Positioner safe?

Low risk

ESB Window Positioner lets localhost web pages read display details and move matching Chrome tabs into fullscreen windows.

Any page under http://localhost/* can message the extension to check installation, request Chrome display information, and ask it to move tabs that match caller-provided rules. The move action uses caller-supplied tab query options and display targets to place a matched tab into a popup window and set it fullscreen.
