I am using Windows XP. When I use Firefox browser, select all and copy and then paste it into some application such as OneNote, it only pastes the text (preserves text formatting) but not the images. I have another PC in which it copies both images and text. Both have same version of FF and mostly everything is the same. I think there is some problem with clipboard. Can you suggest what could be the cause?

I can copy text and images in IE7 on same comp. – Aman Jan 4 '10 at 6:00

This is what solved the problem for me. Set signed.applets.codebase_principal_support to true via about:config. This is not recommended as you cannot limit which sites have these extra privileges.

Refer for specifics and how to do it in more secure fashion.

most likely you are using normal text editor (Notepad, Wordpad etc.) where you paste from clipboard, better use rich text editor like MS-Word (From MS-office suite).

I think it will solve your problem !!

Actually I am using MS Onenote 2007 (part of Office suite). I can paste rich text including images from IE 7 into it but pasting from firefox only pastes the text. – Aman Jan 4 '10 at 6:27
Try using firefox's any add-on like (AllowClipboard Helper,Clipboard Observer,Clipboard-Save-as and Dafizilla Table2Clipboard),it might solve your problem – Mr-Right Jan 4 '10 at 7:02
Ok thanks. AllowClipboard helper seems to work but we have to add each server to it manually. So i took a look at it s documentation and it says that access to clipboard by scripts is disabled by default in firefox. So i enabled by setting signed.applets.codebase_principal_support to true in about:config. It is not recommended though, because of security issues. – Aman Jan 4 '10 at 7:41
