I'm using a current, up-to-date laptop, but for some reason my Facebook messages will send, then a minute later a yellow triangle pops up saying it failed to send. I'll click on the icon to let it retry, but it still doesn't go through. This used to not happen, but now it does all the time. I mainly use Google Chrome, but I've been having problems loading Facebook on that too.. Created by ?. computers-internet-en - internet-en - facebook-en

Mine does the same... Sometimes its because of the internet connection, but otherwise this may sound weird but it could fail to send due to the other person's computer, messages sometimes have trouble sending, especially in chat... My friends computer had a virus, and the message wouldnt send because of it. Weird stuff.. But also sometimes the page just needs to be refreshed before you send another message
