Description of the issue and the proposed solution:
Currently when using the page tweaks menu, it is easy to wipe your configuration by accidentally clicking the reset button:
The button currently has no confirmation prompt of any kind so the user will lose their entire configuration for that site upon mistakently pressing that button.
For consistency, a confirmation should also be added to this Reset All button which is shown when the user clicks '+Erase on the menu (as seen in the previous picture).
