If they make it that complicated to get to their actual content I simply won't read it. I should not be required to block any scripts in order to make a website usable.
It also means that sights with more than 4-5 things I have to unblock go completely unread as I am unwilling to keep going through them to find the non trash sources.
There is an "Allow all blocked for session" button on the extension that will usually get the site loaded for you with one click.
You can also go to the extension options and white-list the domain(s). You can use wildcards there so you don't have to type all the relevant subdomains (e.g. cdn.example.com would be included with a *.example.com whitelist entry).
You can usually copy the link and search for it in Google, and then you can see the post. Or you can use Adblock to manually block the firewall (it sees it as some sort of ad, and removes it as such).
You're not missing much. First it gets mad that the CIA kept a file on Chomsky, then it gets mad that they destroyed this file. And finally, it gets mad that, after the file was destroyed, they couldn't retrieve it anymore.
The CIA has spent years denying that it created a file on Noam Chomsky, but an FOI request has now uncovered an FBI document referencing the CIA file. The CIA file was destroyed at some point, and it is not clear whether that was done in accordance with the Federal Records Act.
What's your citation for the claim that the CIA denied ever creating a file? All I see is denials that the file existed at the time of the FOIA requests, and nothing to suggest those denials were untruthful.
