For last 3 years I loaded CTRL-V a document into a university peer discussion board. I could paste an image. NOW I cant. It isnt the university tech; other students still can. It says in the error message when I use CTRL -V that "Browser does not support pasteing from clipboard.". That is the problem. I want to keep using firefox. But if I have to stop and uninstall you and USE GOOGLE, then I will. Im a customer. Help me.
Thanks

Several FF users have the same problem as me – people with other setting/preferences in FF.
