Good, but a question Rated 4 out of 5 stars

Better than the useless alternatives ive seen so far, just one question, IS there a way of locking one tab to the right split tile and keeping it there regardless of what's on the left side?All i want is one constant tab on the right and browse on the left side, this wants to lock each split tab to another tab, i dont want that, im looking for a way to just have one constant tab always displaying on the right side.If this isnt already a feature it should be

EDIT: Thank you for the response, this is exactly what i want

This review is for a previous version of the add-on (8.5). 

Dual Pane Browsing

Tile Tabs already provides this feature as an option.

To access the Tile Tabs Options window, select 'Tile' on the Firefox main menu, and then select 'Options...'. Alternatively, select 'Tools' on the Firefox main menu, then select 'Add-Ons', then select the 'Extensions' tab, and then click on the 'Options' button in the Tile Tabs entry.

Once in the Tile Tabs Options window, click on the ‘Tabs’ options tab and enable these options:
• 'Assign tab to active tile when untiled tab selected’
• 'Assign another tab when tiled tab closed'

If you now create a new layout with two vertical tiles, you can keep one tab in the right tile, and use the left tile to view any other tab simply by clicking the tab's button (i.e. selecting tabs as you normally do in Firefox). For this to work, you must make the left tile into the “active” tile (e.g. by clicking in the tile’s contents area). If you want to avoid accidentally losing the tab in the right tile, use the 'Show Properties' command (or F1) to set the "tab lock" on the this tile.
