## Review summary

Users find the add-on handy for basic email actions, but reliability is poor. Many report load/login failures and 400/URL-not-found errors, emails failing to open, the Gmail interface requiring the basic HTML view, and intrusive advertising. Overall usefulness for quick checks is offset by stability and usability issues.

### Pros

- Simple and quick to check, send, reply and delete emails.
- Useful for checking incoming emails quickly.
- Seems useful for its intended purpose.

### Cons

- Frequent load or login problems (stuck on login, long wait times).
- 400 errors / URL not found preventing usage.
- Emails sometimes don't open or display content when clicked.
- Gmail can only be used in the basic HTML version; switching between views is unclear or not possible.
- Ads/banner intrusion after installation.
