This is not technically a PROBLEM per se , but hopefully more of a possible SOLUTION for a general problem, for some users anyway. I had been fighting a problem with FireFox updates (I thought) having disabled my Cut-and-Paste ability from practically any webpage to my word processing products (like "Microsoft's Word"). The Cut-and-Paste feature would work if pasted to Window's Notepad, but not to Word. After lots of searching, I found (by accident) a feature in the Environment Backup Extension (FEBE) AddOn feature for Firefox to be causing the problem (for me). Using the "about:config" feature, I searched for "clipboard". I then reset (toggled) the "extensions.febe.copyToClipboard" from "false" to "true". The problem went away. I don't know what issue this may be affecting in the AddOn, but I can do more without FEBE than I can Cut-and-Paste not working.
