Is it possible to get FireFox running on Samsung Galaxy GT-I5700? Would really like to try and get firefox running on older android device.

Have a Samsung Galaxy GT-I5700 which has an ARM V6 800mhz cpu, 250mb internal memory, 4GB SD and is running CyangenMod9 ICS for Spica(GT-I5700).
Am working on getting native apps2sd working properly to try and free up some of that tiny internal memory.
Have not really researched or tried anything regarding installing firefox but a similar question was asked here and thought would post my own q in order prevent bumping somebody elses thread!
PlayStore say firefox is not compatible with my device yet on mozillas website there are older samsung phones that are listed but my exact model is not.
From the Firefox for Android page : Installation requires [...] 384MB of RAM. Your device has only 256MB. You can always try to install the nightly version, although it may be unstable. Or you can search on google for a stable firefox apk.
