This has been going on for about a week now. I use the google chat/messenger portion thats built into the Gmail website. I can paste pics, drag and drop, etc, it all seems fine. I can see the thumbnail versions in the chat. People can send me as well. The problem is once I click any, it normally puts a small darkening filter over the back ground and then does a fullscreen view of the image. in this case it just loads forever. If I right click and try to open in a new tab I get an odd Error 403 message, Your client does not have permission to get URL /chat_attachment/ and then a long string of characters. Ive tried the usual, updated, rebooted, etc. Even in FFox safe mode to rule out extensions. Still not working. FFox 131.0, Windows 11 23H2.
