Hi AliPeterson Hi Mpuzir We need details :-) in order to help you. Can't read your mind :)! #What version of Firefox for Android are you using? FF 37.0.1 (which is the latest)? # What tablet or phone are you using? # What version of android are you using? # Please tell us what you did, what you expected and what happened! As for your specific problem you can delete photos and other downloads through the normal Android Operating system download manager as well as through Firefox's download manager (open the Firefox Settings | Tools | Downloads and then long tap to delete a file or all files) Cheers! ....Roland
