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.

  • It’s a shame the mobile firefox is such a flaming turd in comparison. Can’t imagine using anything else on desktop bit they made me switch to cromite. And the devs gaslight you if you complain about the degenerate ui issues on firefox mobile. I wish there was firefox sync for chromite

      • Been using firefox for at least 3 years (forever on desktop). Try cromite and see, you get all of the same stuff except it’s really fast. No idea why, loading times and all are pretty much the same, but the UI is responsive and doesn’t get in the way. I want to use ff but it makes me want to break my phone

    • On Android Firefox is great.

      • Performance is good
      • you can choose between bottom or top navigation
      • pull to refresh (needs to be enabled in the settings)
      • swipe to change tabs
      • extensions

      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.
