"Start from scratch..." string isn't very intuitive...

[SW1FT]

Instead of being "Start from scratch...", it should be "Reset to default settings".

Agree with you @SW1FT

[ialexsilva]

:+1 simple "Reset All Settings"

[gorhill]

"Reset all to default settings"?

I just want to be sure it is understood that all custom filter rules and whitelist entries will be removed as well.

[SW1FT]

@gorhill yeah, sure.

[Baegus]

That's what the alert is for. ;)

Change button to "Reset to default settings"

An alert after clicking the button saying: "Caution! this will also remove all your custom filters. Are you sure you want to proceed?"
