A browser for Android on Gecko, with the extensions you know from the desktop. Search for uBlock Origin, Dark Reader or Privacy Badger and add them in one tap — they install from addons.mozilla.org, not from a list someone picked for you. Around the engine sits the same quiet interface as the other Simplify apps: a Speed Dial, a tab strip and a menu that only holds what you use.
| Extensions | Search addons.mozilla.org or paste a link, one-tap install, permission prompt, options pages, popups, automatic updates |
| Speed Dial | Your sites as tiles: icon, icon and title, or a preview of the page. Two to six columns, hold and drag to reorder |
| Tabs | A tab strip under the address bar and a switcher with previews. Private tabs go black and leave nothing behind |
| Address bar | Shows where you are, a shield when the connection is secure, and the search engine picker when you type |
| Search | Google, Bing, DuckDuckGo, Ecosia, Qwant, Wikipedia and more, switched from the address bar |
| Library | Bookmarks, history and downloads behind the panel button. Save any page as PDF |
| Pages | Mobile or desktop view per tab, long-press menu for links and images, site permissions with an option to remember |
| Make it yours | Light, dark or pure black, five accents, four fonts, text size, toolbar at the top or bottom, hide it on scroll |
| Keep | Speed Dial and bookmarks exported to one file and imported back on another phone |
| Default browser | Opens links from other apps and can be the default browser |
There is no analytics, no crash reporting and no account in the app. Besides the sites you open, it talks to addons.mozilla.org to search, install and update extensions. Blocking ads is uBlock Origin's job — you install it, the browser does not pretend to.
Experimental builds are on the Releases page — use them at your own risk. Android 8.0 or newer.
You need JDK 17+ and the Android SDK. Use the Makefile, not raw gradle.
make run # install the debug build for the device's ABI and launch it
make apk # minified release APK for one ABI into dist/ (ABI=arm64-v8a)
make apk-debug # debug APK for one ABI into dist/, for testers
make bundle # signed release AAB into dist/, for Google Play
make emulator # boot an AVD
make logcat # follow the app log
make lint # android lint over the debug variant
make help lists the rest. The engine is large, so the build splits APKs by ABI and make install streams the one the device needs instead of copying it twice.
Release builds are signed with the Play upload key from keystore.properties, which is not in the repository. Without it they fall back to the debug keystore, so a fresh clone still builds an installable APK.
With the debug build on a device or emulator (adb from the Android SDK):
adb shell am start -a android.intent.action.VIEW -d "https://example.com" # opens in a new tab
adb shell am start -a android.intent.action.VIEW -d "javascript:alert(1)" # opens nothing
adb shell am start -a android.intent.action.VIEW -d "file:///sdcard/x.html" # opens nothing
adb shell am start -a android.intent.action.WEB_SEARCH --es query "gecko" # search results
adb shell am start -a android.intent.action.SEND -t text/plain --es android.intent.extra.TEXT "see https://example.org"
adb shell cmd role add-role-holder android.app.role.BROWSER app.simplifymy.browser.debug
adb shell cmd role holders android.app.role.BROWSER # lists the app
adb shell cmd role remove-role-holder android.app.role.BROWSER app.simplifymy.browser.debug
Back on a tab opened this way, with no history of its own, returns to the app that sent the link. The offer to become the default browser appears once, about a second after the first normal launch; after adb uninstall app.simplifymy.browser.debug and a reinstall it comes again.
