Doesn't work (XP Italian, FF3.5 Italian) Rated 2 out of 5 stars
Doesn't work on my system: Windows XP SP3 Italian, FF 3.5 Italian
I checked pref.js and I can see the encoded strings of the blocked website (with an w/o the "http://"), but the website always appear in history
I am unsure why this is happening, but here's something to try:
Find your historyblock extension on disk. It's usually around
C:\Documents and Settings\\Application Data\Mozilla\Firefox\Profiles\.default\extensions\historyblock@kain\
Go into the 'locale' folder, and rename the 'en-US' folder to whatever the Italian name is... I have no idea what that would be... post back here if that ends up working or email me directly.
