User reviews
It works. So nice to find an extension that works as advertised. To the developer: keep up the good work, and thank you for a quality product

Brilliant add-on, love it! Option to hide from side bar would be good, I don't use it, nevertheless👍🏻

Bug: if you enable "synchronize settings" on a *new* webbrowser/profile, it uploads these default settings, and "deletes" your original/previously synchronized settings on all other devices... ---- This is extension is awesome, thank you. Best method of saving and sharing webpages. I also love that i can "zap" sections with uBlockOrigin and then save the result <3
