Thank you for writing this add-on, the Google consent really is a nuisance.

The add-on generally works well. However, in some situations I need to turn it off. For example: sometimes, not always, when I want to scroll through search results, the add-on removes the scroll bar and you cannot even scroll using the mouse wheel. I have not found a pattern yet.

Since the add-on contains only CSS and no script, I fiddled around with Stylus and came up with the following CSS that works for me:
-----------------------
#lb
{
display: none !important;
}
html
{
overflow: auto !important;
}

ytd-popup-container
{
display: none !important;
}
iron-overlay-backdrop{
display: none !important;
}
