Html editor doesn't work in FireFox

[testttt]

Hi,
We use Plesk SiteBuilder 4.5 for Windows. But after Firefox 5, HTML editor doesnt work and havent been seen. There are some errors in Error Console: editPageControl editor is not defined. This error also wrote in Firefox support page: https://support.mozilla.org/lt/questions/866115

My screen is like that in firefox: http://img24.imageshack.us/img24/549/sitebuilder.jpg

Will Paralles do anythign for this problem? Because our customers can't use Editor for months.

Have you select edit controller?
You have to select edit controller to HTML then might be work.
