## Review summary

Bluhell Firewall is praised for effective ad and popup blocking, reducing Firefox's memory consumption, and providing strong, silent protection against dangerous sites. However, multiple users report significant issues, including high resource usage causing system freezes, blocking legitimate websites and OAuth transactions, and breaking site functionality. A common request is the addition of a whitelist feature to prevent blocking trusted sites. Despite these drawbacks, long-term users value its functionality when it's working properly.

### Pros

- Effectively blocks ads and popups, enhancing browsing experience.
- Significantly reduces Firefox memory and resource usage.
- Functions silently and quickly when working properly.
- Offers strong filtering capabilities, including warnings about dangerous sites.
- Has been reliable and functional for long-term users.

### Cons

- Causes high CPU and disk usage leading to browser and system freezes.
- Blocks legitimate sites or transactions, including important OAuth logins and business-related websites.
- Breaks functionality on some websites, requiring users to disable the add-on to regain access.
- Lacks a whitelist feature to allow trusted sites automatically, leading to frequent need for manual adjustments.
