If your version of Android supports installation from sites other than the Play store, you can get it. Please note that you will have to check for updates manually if you install that way.
The link to the FTP server directory is on this page: https://wiki.mozilla.org/Mobile/Platforms/Android
Yes you will have to manually install new versions if you do not install from Google Play.
If you have a ARMv7 device the you may want to download the fennec-18.0.yourlanguage.android-arm.apk instead of the multi version as it is a bit smaller
