In order to measure the user experience, Firefox collects a wide range of anonymized timing metrics related to page load, responsiveness, startup and other aspects of browser performance. Collecting data while holding ourselves to the highest standards of privacy can be challenging. For example, because we rely on aggregated metrics, we lack the ability to pinpoint data from any particular website. But perhaps even more challenging is analyzing the data once collected and drawing actionable conclusions. In the future we’ll talk more about these challenges and how we’re addressing them, but in this post we’d like to share how some of the metrics that are fundamental to how our users experience the browser have improved throughout the year.
On Android Firefox is great.
Can handle my more than 100 open tabs quite well.
Performance is not good at all. I have a 120hz phone now and scrolling feels like Firefox is still on 60hz. Settings and the like are perfectly smooth tho, so it’s not actually only rendering at 60hz, it’s just rendering webpages so slowly that it can’t keep up with my screens refresh rate.
Feature-wise Firefox is way better than Chrome on mobile but performance is just horrible. Firefox also looks a little dated on mobile by now, especially compared to Chrome but that’s not a deal breaker. Would be nice if they adopted Material Design 3 tho.
No, sadly performance is not good. With less installed addons and no opened tabs it takes more time to start up than the old version, which had a few dozen opened tabs opened and more addons.
It also lags quite a lot while in use after startup.
