Edit: I’ve moved this topic into the Feature Requests section so it can be voted on directly.
Edit 2: The Themes and Styles feature has been released and includes a Custom CSS feature which can be used to hide all green ‘toast’ messages:
.toast.green { display: none }
Alternative method using Fully Kiosk Browser's Inject JavaScript Feature
In the meantime, if this is on a device running Fully Kiosk Browser, you could use the “Inject JavaScript” feature in Advanced Web Settings to inject a style override that hides the toast:
let css = document.createElement('style');
css.type = 'text/css';
css.appendChild(document.createTextNode(".toast.green{display:none}"));
document.getElementsByTagName("head")[0].appendChild(css);
In the example above, I’ve hidden all green toasts which are primarily success messages (eg. .toast.green
). You could target the .toast-container
for ALL toasts, but I would not recommend it as some error or informational toasts might be important.
