Pros
- Open-source and community-driven browser (fork of Firefox) that prioritizes privacy with full code transparency on GitHub and no telemetry .

- Highly customizable tab management with vertical tab columns, split-view for multitasking, and "Zen Mods" for personalized UI adjustments .
Cons
- Performance lags behind Chromium-based browsers—benchmarks show Zen scoring 31.6 vs Chrome's 37.7 on Speedometer tests .
- JavaScript debugging can be flaky with unreliable variable watch lists and occasional skipped breakpoints in developer tools .
- Lacks standard platform conventions; for example, Cmd+W doesn't close the last tab's window by default, requiring manual about:config tweaks .
