When you launch mobile Firefox (Fennec) 1.1, you'll see that it has a new start page. In portrait, it looks like this:

Through the start page, the browser's providing a couple of things that are of interest particularly when you start up:
We're also taking advantage of having your attention for a second to show you a maximum of two recommended add-ons that you don't yet have installed. Tapping on one will open the add-ons manager and let you install the one you're interested in right there. While looking for add-ons is not necessarily a start-up task, add-ons are a huge part of what makes Firefox such a great fit for its users, so interjecting quickly to show people what's new and worthwhile seems like a reasonable thing to do.
Here's the page again, in landscape:

This page is a change from 1.0, in which the browser used to display the awesome screen immediately (Fennec's display of frequently visited pages and bookmarks, as well as from where you search the web). We were finding, though, that people were finding it disorienting - people were launching the browser, and expecting to see something that looked like a browser. Going to the start page instead helps with that problem and also helps with some frequent just-opened use-cases. Oh, and if you already have a start page that works for you, you can switch to using that over in preferences:

We're not done, of course. Heading towards version 2.0, I'd like to explore more of how we can use the start page to help people see what's new on the parts of the web they care about since the last time they connected with their online lives. I've written about some of this here before, but it's a topic I'll be writing about more over the next few weeks.
