Hi Medusa, The amount of storage Ribbet is requesting (1MB) is a minuscule amount. We would simply use this amount without asking (that’s what a program you installed on your computer would do), however Adobe Flash requires that we prompt you to do so. Ribbet really needs this space to function effectively and I would suggest simply approving it to use this amount of memory. Such a small amount will not have any impact on your other programs or storage space.
Unfortunately there isn’t a way to stop this dialog from appearing as Adobe Flash requires this amount of space to run Ribbet effectively, and so it will keep asking until you allow it. All of our regular users have allowed this dialog without any issue. If you have any further concerns please let us know.
