Mozilla will have built-in phone and email masking
Mozilla build in a Firefox Relay extension that generates the user's email aliases and phone numbers directly into the browser. The extension was first released in 2020 to protect user accounts from spammers.
Firefox Relay creates aliases for the user's phone number and email, which allows you to anonymously register on sites that require you to provide personal information. The extension creates up to five user email masks for free. You can create different camouflage phone numbers and email addresses for each site, making it harder for spammers. The Firefox Relay extension will be built into Mozilla within a year. In November 2022, Mozilla Firefox was recognized the second most vulnerable among browsers - over 117 vulnerabilities were registered in a year.
