Prevents the opening of the site bankir.ru in Thorough mode in FF4 Rated 5 out of 5 stars

Very nice extension, but in FF4 has an issue:
initially, the page http://bankir.ru appears on a couple of seconds, then cleaned and left empty :(
If you turn off Thorough mode, everything works as expected.

Exactly the same problem occurs in FF4 with MR Tech Link Wrapper add-on.
