Just right-click on any input text field and you'll have the option to insert a unique test email address. The extension uses a timestamp to ensure each email address is unique and is customisable. Email Address Customisations: - Prefix the email address so you can use your own address with a '+' modifier (so you can still receive emails, depending on your email provider). - Choose a common domain, or use a custom one. Example: myemail+20221104172905@gmail.com I can imagine this extension will be useful to just a small few, so if it's useful to you, leave a rating and let me know.
