Hi This does not sound like an issue with Frefox for Android, but I will try my best to help. The best way is not to publish your photos to any open website, but I appreciate the that may still wish to share them. Assuming that is the case, I recomend looking at the privacy controls of a number of different sites, and possibly publish one test picture, log out of the site and see if it can still be viewed. I hope this helps.
