Chrome browser add-on
I am not sure it will work out asking people to stay on a website to provide a circumvention help. How many people will forget about it? How annoying is it for people to always have an extra tab open? How many people are using only one tab?
Why not create browser add-ons for the most popular browsers?
The add-on could remember to always internally open the flashproxy website but hide it from the user. It would be a Tor Bridge (flashproxy) Browser Add-On.
