Whether this add-on works with your flash pages or not, highly depends on the wmode needed to operate that flash, because the add-on changes the wmode and thus renders some significant number of pages unusable while the add-on is enabled (they either don't load at all or they're missing parts or become unresponsive).

There's no risk involved with this - just be prepared that it may not have the same results on every flash page.

There's also not much the add-on can do about that.
