The browser landscape has shifted dramatically in 2025. As developers, we need to understand these changes to:
Optimize our workflows
Build cross-browser compatible apps
-
Protect user privacy
Performance Benchmarks That Matter
# Run your own tests using:
npm install -g browser-bench
browser-bench --tests=jetstream,memory
Key Findings:
Safari leads in raw JavaScript speed (225 vs Chrome's 210 in JetStream)
Firefox uses 30% less memory than Chrome with 10+ tabs
-
Chrome still wins for WebGL rendering and CSS feature support
Privacy Tech Deep Dive
Firefox's new Tor Integration Mode includes:
First-party isolation
Resist fingerprinting
Automatic HTTPS upgrades
/* Firefox-only privacy feature */
@supports (-moz-private-browsing: true) {
.tracker { display: none !important; }
}
Actionable Recommendations
- For Web Apps:
# Test in all three using Docker
docker run -it browser-test chrome,firefox,safari
2.For Extensions:
Chrome: Most APIs
Firefox: Best privacy controls
Safari: Limited but growing
3.For Battery-Sensitive Work:
// Safari wins on MacBooks
if (navigator.userAgent.includes('Mac')) {
recommendBrowser('safari');
}
