Obviously I'll adjust my rating if there's something I'm missing, but this extension seems to just open windows and put them next to each other instead of partitioning the content frame.
Tile Tabs WE has the same basic objective as the original Tile Tabs - to display multiple web pages in a tiled layout - and it does that!
Tile Tabs WE works differently to the original Tile Tabs, because using the WebExtensions API's, it is not possible to display multiple pages simultaneously within the same browser window.
