User reviews

Its the only barely functional split view for firefox despite YEARS of begging them to create one. Edge, Chrome and Opera all have it. This extension is not perfect. You cannot resize this side window. its fixed for me. But its better than absolutely nothing.

Has potential, but every time I close it, the page is gone, and I have to open again. Plus, an autohide and show on hover would be great. (Tested on Zen)

Excellent addon. However, it's not clear if the site open withing its pre-defined container. If the developer reads this, please clarify. Thanks!
