User reviews

The mail.com MailCheck Firefox add-on was praised for its convenience and time-saving email checking features on multiple accounts and other browsers. However, multiple users report critical issues with Firefox compatibility: inability to log in due to broken password prompts, login button becoming inactive, and the extension freezing. There are also concerns about excessive permissions demanding access to unrelated data, impacting user trust. Overall, while it worked well earlier and on other browsers, the current Firefox version is largely non-functional and frustrating.
Pros
  • Saves time by allowing quick checking of mail accounts without missing emails.
  • Convenient way to view emails from multiple accounts.
  • Worked well on other browsers like Chrome and Brave before issues arose.
Cons
  • Currently does not work properly on Firefox; users cannot log in or get stuck on the login screen.
  • Login process is broken—inputting email disables the login button and never prompts for password.
  • Requires excessive permissions, raising privacy and security concerns.
  • Extension compatibility with latest Firefox versions is problematic, with no recent updates.
  • Extension freezes or hangs after installation on Firefox.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

mail.com MailCheck requires a lot of sensitive permissions. Exercise caution before installing.
