I've installed firefox android but now have low memory alert, went to "manage apps" to move ff to sd card, "move to sd" is not functioning, is there anything I can do, if not is it not possible to run firefox from sd card, it takes up a few mb of storage. I've found that the cache can be moved to sd, is this the only fix possible - tho someone has posted a warning saying it's not a good idea because of constant writing to sd limits sd life. help!
