User Reviews

Dobrze, że obsługiwane są od razu kilka języków. Praca z klientami z różnych krajów stała się znacznie łatwiejsza.

It used be good but it's gotten bad now

This tool has been instrumental in our team's communication efforts. We're a small startup so we need our emails and proposals to look professional without hiring a full-time editor. The team style guide feature ensures everyone writes with the same tone and formality level. Integration with gmail means fewer embarassing typos in client communications

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.

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
