IMPORTANT NOTICE
Why Tile Tabs WE is different to the original Tile Tabs
Tile Tabs WE works differently to the original Tile Tabs because of changes that Mozilla is making in Firefox 57.
The original Tile Tabs was developed using technologies that are no longer available in Firefox 57.
Firefox 57 and later versions will only support add-ons that have been built using the new WebExtensions API's (which are the same as the Chrome extension API's).
Using the new WebExtensions API's, it is not possible to display multiple pages simultaneously within the same browser window. This is why Tile Tabs WE has to move each tiled tab into a separate window.
It is hoped that Mozilla will provide a new WebExtensions interface that will allow a new add-on to be developed that is more similar to the original Tile Tabs.
