Hi FB Photo Zoom for Chrome enthusiast,
I understand how troubling it can be when you get a scary message telling you some software can do things you may not have been aware of. The good new is that is not the case with FB Photo Zoom
You can rest assured that FB Photo Zoom does not access, view, use, manipulate, or even care about any of your Facebook or browsing data, history or private information, at all.
Since FBPZ was first released years ago we've had a set of permissions that allow the extension to run and operate on facebook.com as well as across your multiple tabs with facebook open. Chrome, of course, let's you know that the extension runs on facebook.com. In addition, FBPZ requires a permission called "tabs" which, unfortunately, triggers a warning in Chrome stating that FBPZ can access your browsing activity. Of course, FBPZ does not access your data, even if it could according to Chrome. You can read more about this specific permission here, on Google Code's docs
On June 5th, 2012, as part of a release to fix a lot of changes Facebook was making to the timeline, we also added a web-permission for this domain, regisgaughan.com so users who contact us with issues they've found in FBPZ, we can better understand what's happening. In doing so, Chrome has let you know of the other permissions once again, even though they are not new. No new permissions have been added beyond this domain.
Again, this extension does not access, nor would it even want to access, any of your browsing data or personal information, even if it could. FBPZ only cares about zooming photos. It's unfortunate that I cannot continue to innovate without these silly warnings.
Thanks for enjoying FB Photo Zoom,
Regis Gaughan, III
