Rated 3 out of 5 stars

no matter the flash app/game, FlashResizer doesn't do anything if you're using firefox 56.

Rated 3 out of 5 stars

some flash-apps are made to resize between a small window and a larger 'semi-fullscreen' one.
FlashResizer prevents the app from doing it's own resizing, which is problematic when small and large do not share proportions as FlashResizer keeps it at the small-window-proportions.
