FoxBox allows you to run desktop Firefox on an Android device.

What is FoxBox?

FoxBox is not Firefox itself and is not a Mozilla project, but instead is a compatibility layer that sets up a Linux desktop Firefox build, launches it, renders it and provides a way to interact with it.

What features does it provide?
*Web page rendering
*Standard desktop Firefox extensions
*Built-in file manager. Can interact with files on sdcard, after you give it permissions.
*Developer tools.
*Sound support.
*Etc

How to Use FoxBox?

Use it just like normal. But here are some specifics to the app.
* Tap with one figure to click.
* Pinch to zoom.
* Slide to fingers up and down to scroll.
* If you want to bring up a keyboard, tap on the screen to get a set of icons to appear and then click the keyboard icon.
* Hold and slide one finger to pan (useful when zoomed in).
* If you want to do the equivalent to a right click, tap with two fingers.
* If you want to change the scaling or the dns settings, find the service android notification and click the settings. You have to stop and restart the app after changing these settings for them to take effect.

Why Use FoxBox?

Desktop Firefox has a different set of features than the Android mobile app. Also, websites behave different when opened in a desktop browser vs a mobile browser (even when you say you want the desktop version of a website).
