very bad update. I returned to older version 1.1.8.1-signed.1-signed.
because, i cant import my list from older version's export.
also in new version, first opened blocked site and then diverted to another link. but in older version, the mozilla can't open blocked site.

in older version when any site blocked, you receive a notify in down right corner and it hides automatically. but in new version, I need to close the notify from top of the window .
