TYPO3 Core

First some clarification: I know that copy, cut, paste with the buttons never has worked in Firefox without either using AllowClipboard Helper or manually configure user.js. But copy, paste, cut with Ctrl+ has worked perfect until TYPO3 4.2.0. So it's a change in the 1.7.x version who causes this partly annoying behavior (when you are used to the possibility).

But strictly this behavior could be seen as a bug.

In versions before 1.7.x this behavior (use of shortcuts) work perfect regardless of the copy, cut, paste buttons showing. In version 1.7.x and uppwards it only work when copy, cut, paste buttons are hidden, therefore the following works.

RTE.default.showButtons = *
RTE.default.hideButtons = copy, paste, cut

but not

RTE.default.showButtons = *

Another problem is no message which can explain the behavior. A third problem is that AllowClipboard Helper isn't official in the Fx addon repostitory. Configuring user.js is to complicated for a average user.

TYPO3 version has to be 4.2.x and higher

1. Copy some text into the RTE with only default settings of htmlArea. Use Ctrl-C and Ctrl-V. It should be possible to copy in the text.
2. Set Page TS Config to RTE.default.showButtons = * Try to copy with Ctrl-C and Ctrl-V. Should not work and no message. Buttons should not work, with no messages.
3. Set Page TS Config to.
RTE.default.showButtons = *
RTE.default.hideButtons = copy, paste, cut
Copy should work.

Solution/possible
1. Get the message about configuring user.js/AllowClipboard Helper back and also a message that with hiding the buttons copy, paste, cut with ctrl-c etc will work (or stated in the manual)

2. Make the copy, paste, cut work whatever configuration used in Page TSconfig, and whatever method used

Maybe there are another solutions.
