CloseReview for Focus Regainer Lite by harl windwolf
Rated 4 out of 5 stars
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.
