Hi people.
Recently I installed new, 4th version of the Firefox. It's all sweet and dandy but I encountered a problem with the page that is my homepage.
This is my page:
http://www.onet.pl/There is a sidebar to the left that can be modifed by user, like select city ("Krakow" should be default), change the order of the tabs (I like to have currency and stock exchange tabs at the top), close the unused tabs and move them to bottom, or move the whole sidebar to the right (which I prefer).
My problem is that when I refresh this page, or restart the browser, it switch back to default set (wich isn't bad...if you live in Krakow

).
Can somebody with FF 4 (Polish user would be mostly welcome, but any foreign Good soul is welcome too) check if they have same problems with this page?
I want to check it to find out if it's:
A) FF 4 bug
B) My PC bug
C) Onet.pl fault (which is known for problems with anything diffrent than IE

)
I tried google for similar bug but the only thing I found was same question for FF 3.6...with no answer

Edit: BTW,
NO it's not normal behavior, coz in previous version of FF this page always saved all my settings, even after the browser restart.
Thanks for help.
