Chrome does this to you. Perhaps derivatives of Chrome do as well. In any case...
Type "Chrome://plugins" into address bar.
Look for "Adobe Flash Player"
Check "Always Allowed to Run"

Doing this means Flash will run on every site you visit. If you visit "suspect" sites, this can be a bad thing and could lead to virusy stuff. If your browser history doesn't resemble the guest list of the last AVN Awards then you should be ok.
However, I am obligated to say that you have been given a fair warning.
