Just like FitText, this extension makes font-sizes flexible. However, this one does not use JavaScript. It is a pure CSS solution and uses the vw unit for the font-size.
This means the text size will follow the size of the browser window (not the size of the object’s container!)

You can download the new extension via the Extension Manager: Menu->Tools->Extension Manager->Online Gallery->Miscellaneous
Note:
This is an extension from my private collection. It is shared "AS IS".
