[TYPO3-calendar] realURL- event URL problem in FF

[Ani H.]

Hello list!

my URL of an event looks like this:

http://www.community-of-knowledge.de/kalender/details/2011/05/21/event/titel/vienna-knowledge-space-2011/view-month|page_id-70/

the URL leads to the monthview and not to the event. it has the same 
baheviour if you click on an event from the listview (which works) and 
then go to the browser bar, click on the link and then again "enter"
-> leads to the monthview startpage:

http://www.community-of-knowledge.de/kalender/details/2011/06/08/event/titel/ismick/view-list|page_id-79/ 


this problem does not happen in IE, the event links work fine. has 
anyone the same problem and/or a solution?

i am using typo3 4.5.2, cal 1.4.0, realurl 1.11.1 and firefox 4.0.1

thanks!
