- Security -
This extension allows Furiffic access to the sites listed above.
Only the import page can request that this extension is enabled internally.
When leaving the import page or every 60 seconds(in the event that the tab crashes before notifying), the extension is disabled internally to prevent any other page accessing the above listed sites.
These precautions have been taken for security reasons to prevent abuse in the event that Code Injection vulnerability occurs on Furiffic.
-- The chances of these situations colliding is very slim, but to ensure absolute security it is advised to disable this extension when you are not importing into your gallery via (chrome://extensions/).
