Rated 4 out of 5 stars

I only used it at one flash game that I liked and there it worked great. There should be a possibility to give the symbol into the context menu (of flash content) or to an other bar, Because I use it that rare, so the symbol wastes the appbar space.

A great idea, but...

... I'm afraid I haven't the time or money to spend on such an upgrade. I did in fact plan something along these lines (an option to insert a button next to any zoomable Flash content on the page), but since this would be quite a lot of work, and since this extension isn't exactly making me rich ($27 donated so far, despite 50K users over four years), I'm afraid it isn't likely to get done anytime soon (unless I win the lottery or some such).
