User reviews

Users appreciate the add-on's ability to quickly show email counts and its general functionality for supported accounts. However, it lacks support for some 1und1 domains and struggles when users access through VPNs, leading to frequent password changes. There are compatibility issues with the newest Firefox versions and unexpected behavior such as resetting the search engine without user consent. Additionally, adding multiple email accounts sometimes doesn't work as expected, causing frustration.

Pros

Allows immediate viewing of email counts for different addresses
Generally works well for supported email accounts
Simple and user-friendly for basic email notifications

Cons

Does not support certain 1und1 domain endings like online.de, onlinehome.de, and e-mail.de, causing inconvenience
Frequent false password change requirements due to VPN usage being flagged as suspicious by WEB.DE
Compatibility issues with the latest Firefox versions, with some users experiencing 'unsupported browser' errors preventing access
The add-on resets the default search engine to web.de without clear consent, raising privacy and legal concerns
Adding multiple email accounts can fail without feedback, making management difficult

Muss andauernd mein Passwort ändern, weil Web.de VPNs nicht kennt und es anscheinend als verdächtige Aktivität aufnimmt, wenn man mit einem VPN ins Mailkonto geht... Dem Support habe ich dieses Anliegen UMFASSEND geschildert und als Antwort kam sinngemäß "Wir können ihn leider nicht weiterhelfen"... keine Worte...

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.

WEB.DE MailCheck for Firefox requires a lot of sensitive permissions. Exercise caution before installing.
