Google Container Shortcut v1.6
This add-on opens a new tab in the current browser window, creating a new session inside a Google Container. The extension uses Firefox's multiple containers feature. It creates a new Google container if it doesn't exist, or just uses the existing one if it does.
The add-on also adds a new option to the right click menu whenever text is selected, allowing users to search that text in a new Google container automatically.
Users can change the add-on preferences to choose if they want the containers to switch manually or automatically depending on if the tab is on a Google page or not.
