@nalcalag The privacy protections dialog works as expected, nice work!

After continuing with the onboarding, however, I noticed that these screens are still not scrollable (see the screenshots below). A similar fix could be applied to them as well, WDYT?

@0nko thanks for the review! I can't see the images you attached, but I assume you're referring to the Dax dialogs on the new tab page once the browser is visible. I agree they should be scrollable, but since they don't block browser usage and fixing this would require handling the keyboard responsiveness within the browser content, it's out of scope for this task. Hope that makes sense!
