If you want the most stable version of Firefox, I would install the release. If you want new features 6 weeks before they are released and don't mind the risk of crashing more often, I'd install the beta. It's up to you.

Thanks Tylerdowner

Hi,

Just to add to what Tyler said, if you are using Sync, you can only have one version installed, either release or beta but not both (from that perspective, it does make a difference).

Thanks for using Firefox for Android! Michelle
