Pros
- Provides strong privacy and security protection including blocking malware and unsafe websites.
- Effective at blocking ads and trackers, improving browsing experience.
- Gives warnings about potentially unsafe or spammy websites while allowing users to proceed if desired.
- Transparent about data usage with some concerns about permissions being necessary for functionality.
Cons
- Causes significant browser performance issues including memory leaks and high memory usage, especially with multiple tabs and certain protection settings enabled.
- Interferes with site functionalities, notably causing issues with ReCaptcha and services like Outlook and Gmail, requiring disabling protections or the add-on entirely.

- Lack of clear support and instructions for features like allow-listing makes resolving issues difficult.
- Slow update approval process on Firefox leading users to run outdated versions compared to other browsers.

I love the privacy and security options it gives, but any site that uses ReCaptcha fails to let me log in because the plugin disables and blocks it, so I need to disable the ads/trackers setting for those sites.
