Hi mforsetti, this could not be reproduced since 'Take a screenshot' button design has changed. In latest versions, Nightly 90.0a1 (2021-05-13) (64-bit) and Release 88.0.1 versions, after disabling button, a message will appear in the bottom right side, reading 'We can't screenshot this page...', it won't be grayed out again. Thank you for taking the time to submit this bug report, and please, feel free to reopen it if you have any troubles. Regards, Jerónimo.
