If you're going to be supporting app development on Android (and you should), you might as well pay for the best content you can. That's what the Google Play App Roundup is all about. This is where you can come every week to find out what's new and cool on Android. Just follow the links to the Play Store.
Most browsers for Android seem to focus on adding more features, but Firefox is focusing on something else with the aptly named Firefox Focus. This is a stripped down browser that preserves your privacy and offers a fast browsing experience.
When you open Firefox Focus, all you have is a bar in the middle of the screen for a search term or URL. The default search engine is Yahoo, which is kind of weird at this point. You can change it to Google, and I'm sure most people will. The app has an interesting purple and pink color scheme with a gradient sweeping across all the UI elements. Gradients usually look pretty old-fashioned, but I think it kind of works here. Firefox Focus has a neat 80s vibe.
Firefox Focus uses ad-blocking and do-not-track by default on all pages. Additionally, it saves no data locally. While you're browsing, there's a floating action button in the lower right corner with a trashcan on it. You can tap that at any time to close your page and delete all browsing data. Additionally, there's a notification whenever Firefox Focus is running. There's even a "Stealth" mode that prevents screenshots and app previews in overview. You can turn that off, though.
You only get a single page at a time in Focus, so no tabbed browsing. That makes sense considering the mission of Focus to provide simple, fast browsing. The overflow menu shows you how many trackers were blocked on each page, and there's a toggle right there to shut blocking off. That's useful on pages where there's ad-block detection that blocks you from seeing content. The menu also includes options to open a page in Firefox or your default browser.
Using Focus for all your browsing is tedious seeing as there's no bookmark system, history, or tabbed browsing. You can set it as default, if you want (there's a toggle in the settings). However, it's a good choice for opening links from other apps as it'll block all tracking and doesn't keep history. Some of the privacy features are a bit heavy-handed, but that's what you get in a privacy-oriented browser.
