Would be nice to be able to access the interface without actually having to run a search in Google.

As this extension is "developer-friendly" I might miss something ? But after adding it to Firefox Quantum 60.0.1 (64bits), the icon does not appear in the UI.
There is a similar extension for Chrome that works perfectly : it adds the extension icon on each result of the google webpage and a simple click on this icon enables or disables the filter. Too bad I have to go back to Chrome to filter overwhelming sites like pinterest.
Any advice would be welcomed.
Cheers, Han.

Don't hesitate to contact me if I can be of any help.

Works okay, needs more customization like colors.
