The Firewall list is difficult to use particularly if you have low vision. The tiny country flag icons are difficult to see and if you hover over them nothing is displayed. Would be great to add hover text with the country name at least. Also, clicking the checkboxes in the filter control requires clicking precisely on the checkbox input rather than being able to click on the input label to check / uncheck the item which is far easier for people who have difficulty seeing or are using an alternative input device.
