[TYPO3-rte] firefox: allowclipboard helper not recognized

[Steffen Miebach]

Hi,

if I want to paste something from the clipboard with the little button 
in TYPO3 4.5 (rtehtmlarea 2.1.5, firefox 3.6.13) pops up a warning that 
i have to install the allowclipboard-addon. i've done that (vs. 1.0.1), 
restarted the browser, emptied cache, cookies etc. but the warning pops 
up again. if i install the addon again, it remains the same.

bug or have I done something wrong?

greets
