No they don't store in your computer
'''''You can't'''''
Have messages sent to your email rather than the phone.
No, you cannot typically read the messages of someone's inbox on the Facebook website. You may be able to read someone's messages if they used your device and did not log out from the Facebook website.
The first programmable computer, the Colossus computer, was designed and employed by British codebreakers to help read encryped German messages during WWII.
unread messages are messages that have never been opened or mark as read basically not read
A SMS gateway is the method used to in effect allow SMS messages or text messages to be generated or read using a computer. Most of course are on the cell phone network but increasingly they are accessible from a normal computer.
an inbox on facebook is where people can email you messages that only you can see. After you receive their message and read it, you may also reply to it.
You can buy the e-book from the Pottermore store and read it through that.
You could download Mozilla Firefox instead of Internet Explorer, or you could download Cleanup.exe from Steven Gould's website. It's free and easy to use, and will clean all Internet traces on your computer. However I think you are confused about history. Facebook does not store any chat history on your computer in the form of any temporary files, however your boyfriend has been able to find out your log-in password for Facebook and has looked at your conversation history through your online account. There are 2 steps to cure this: 1. change your Facebook password to something that is hard to guess; use numbers in the password to make it more difficult for other people to guess. 2. change your boyfriend, for one that has a little trust & faith in you.
What?
I don't believe you can unless you're logged onto the site. I guess you could print it or save it to your computer and then read it, but I'm sure that's not what you mean. :P
Definitely not illegal. It's not exactly nice, but it is his fault for leaving it open. If my girlfriend leaves her facebook open, I don't touch it because I know there are things I just dont want to know.
