Tob s (ID: 000000f943801ead) Voted 1 ★ - Updated 09/22/2023 Would not reccomend. Screenshots that are supposed to be taken do not load at all, doesn't matter the configuration. Live testing worked for the OS & Browser that I was already using, but not for other OS and Browsers. This makes the extension pretty much useless/pointless. Tried the free plan for less than an hour. It will require you to create an account, but you won't have any account settings, if you'd ever want to delete the account.
