My impressions with web browsing on the N900

I’ve recently had the pleasure of testing Firefox on the brand new Maemo based Nokia N900 phone (which I blogged about previously), and I have to say I’m impressed. Of course, I’m biased — I love Firefox. I’ve been using it since the Phoenix days and it’s almost part of my DNA these days.

However, I have a confession to make: Firefox isn’t yet my default browser on the N900. I think it will be very soon, but right now, my browser of choice on this particular device is another Mozilla-based browser: MicroB. It’s actually the best web browsing experience I’ve ever had on a mobile device (but to be fair, Firefox is the second best experience, so it’s definitely up in the same league already).

Allow me to summarize my initial impressions with both of these Mozilla browsers:

  • The Awesome Bar in Firefox is… awesome. I never actually reflected on how convenient it was to use until I tried MicroB, which forces me to remember URLs again.
  • Weave is probably extremely useful, too, but since I’m using the latest trunk builds of Firefox (“Fennec”), I can’t actually use it.
  • I’m not completely sold on Firefox’s UI model of showing controls on a surface on the sides of the web page. I’d be curious about whether there has been any usability research that suggests it’s better than the more traditional toolbar at the bottom of the screen. Btw, I’ll follow up with some ideas about this in a future blog post.
  • I’ve fallen in love with the volume rocker zoom in MicroB — it’s smooth, fast and surprisingly accurate. Would love to see this in Firefox!
  • When double tapping to zoom in MicroB, a subtle zoom animation is used which feels intuitive and responsive. In Firefox, the zoom is instant, making it feel less fluid.
  • The default page zoom in Firefox is designed to make the full width of the page fit on the screen. This unfortunately has the side effect of making the text on almost all web pages too small to read. It seems like MicroB has chosen a different approach where the default zoom includes about 800px of the web page width, which makes it possible to read most pages without zooming in.
  • Actually zooming in on a page in Firefox is a bit tricky, because it auto-zooms on the object you double tab on, even if that object is only e.g. a small image. This means that you often zoom in too much, and since it’s not possible to adjust the zoom level in an easy way (keyboard shortcuts don’t cut it, especially not for me since I have the Scandinavian keyboard layout where [Ctrl]+[-] doesn’t work), you have to double-tap again to zoom out and then try again.
  • MicroB feels more responsive when panning around on a page. This is mostly due to the fact that the UI and panning is done in a separate process from the actual Gecko web rendering process. At FOSDEM, I was pleased to hear in the Mobile talk by Mark Finkle that Firefox will make full use of the Electrolysis technologies that are currently being baked. What this means, in simple terms, is that Firefox will be just as responsive as MicroB in the future since the web rendering process will be separate from the UI/frontend. I can’t wait to see the results of that (which of course will benefit desktop Firefox as well).
  • The checker pattern seems to show up more frequently on the screen in Firefox compared to MicroB. I don’t know if Firefox is just more conservative with how much of the web page it pre-loads off-screen, but sometimes it can cause the whole screen to remain “blank” for a few seconds, which rarely happens with MicroB.
  • The Back button history in MicroB is a good idea in theory: when clicking the Back button, small thumbnails of the previous pages are shown, making it easy to pick the page you want to get back to. However, the implementation sucks because it takes several seconds to load these thumbnails and the thumbnails are big enough that you have to pan around in order to see anything more than one page back. Would be nice to see some kind of combination of Firefox’s and MicroB’s implementation: when tapping on the Back button, Firefox would simply go back to the previous page, but when tapping and holding, it would show a pop-up with preloaded thumbnails in a similar fashion as with MicroB, except without the delay. (Maybe the actual thumbnails could be recorded when you navigate away from a page?)
  • Flash — as much as I hate it — works pretty well in MicroB out of the box. In Firefox, I have to enable it manually, and the responsiveness of the UI with Flash enabled isn’t great. Can every web site switch to open video, please?

I personally feel that both MicroB and Firefox are really good web browsers, and the fact that they’re both powered by Mozilla’s Gecko web rendering engine is a huge plus for me. So in a way, I don’t feel bad for not using Firefox primarly right now, because my current web browser of choice is still filled with Mozilla love. :)

That said, I can’t wait to use an Electrolysis-powered version of mobile Firefox later this year!
