Containers On The Go от ContainersOnTheGo

The add-on allows you to open different accounts on the same site at the same time, improve privacy by separating social media from your regular browsing and avoid ad retargeting by opening shopping sites in their own container.

The add-on will instantly create new containers for the new tabs. The containers are automatically removed when the tabs are closed.

• The add-on requires the Container Tabs to be enabled in Firefox. The Container Tabs can be enabled from Options -> Privacy -> Container Tabs
• The tabs can be opened by clicking on the toolbar button or using the Alt+C shortcut
• You can open a link in a new tab-container by right-clicking on it and choosing the "Open link in a new container"
• The right-click menu choice can be disabled from the Add-on Options page
