Review summary

Users generally praise ff2mpv as simple, lightweight, and easy to customize, and as a reliable way to bypass Firefox's HTML5 video issues, especially on older hardware. Install is straightforward, and it’s perceived as low on permissions. However, reliability varies: several reports of it stopping unexpectedly, silent failures, or not working on some OSes (Linux Wayland, macOS Ventura). Some dependencies (youtube-dl/yt-dlp) updates and occasional redundancy with other tools also complicate use. Overall, strong on performance but not consistently dependable across environments.

Pros

Works great and easy to customize.
Simple and lightweight with low permissions.
Helps bypass Firefox's HTML5 video player issues.
Good performance on old or low-spec hardware.
Install and setup are straightforward.

Cons

Reliability is inconsistent: it sometimes stops working or silently fails.
Does not work on certain OS/environments (e.g., Linux Wayland, macOS Ventura).
Depends on external tools like youtube-dl/yt-dlp, which require updates.
Some users find the feature redundant with other tools (e.g., Tridactyl).
Occasional lack of error messages or logs when it fails.
