Firefox 12 for the N9 just released

Back in February I witnessed the release of Firefox 10 for the Nokia N9. In March Firefox 11 was released and now Firefox 12 arrived to the N9 Nokia Store!

While overall I believe there’s a slight improvement on the browser performance, there is a couple of things I didn’t like:

  • The update from v11 failed to install. Although it downloaded the installation package successfully the phone wasn’t able to complete the update. Rebooting the phone didn’t help. I had to uninstall Firefox v11 first and then I was able to install Firefox v12. Not a very elegant solution for a problem that shouldn’t exist in the first place.
  • The javascript performance not only didn’t improve but actually got worse. Not slightly worse but significantly worse: 3845.1 ms, which is disappointing compared to the result Firefox v10 achieved (3284.8 ms).
Meanwhile I finally got the PR1.2 update. It took a long time to receive it because apparently Nokia delayed almost two months the release of the update for the unlocked “Country Variant” devices like mine. I installed it as an update over the air (OTA).
Now I’m wondering if this kind of delta update is somehow influencing the bad Firefox 12 javascript performance and if I had used NSU (Nokia Software Updater) to install the complete PR1.2 firmware image would have helped the overall phone performance.
