I´m on Firefox with “Adblock Plus”, NoScript, Ghostery and a couple of other addons.
I was able to download some addons when pausing Adblock Plus for fs.to.
BUT: other addons additionally needed Ghostery to be paused temporarely, otherwise i just got this red warning page, telling me to deactivate things or go premium.
So they may have several “levels” applied during the last days. Addons which i havent updated for a couple of days seem to be a bit less critical in what we need to deactivate than addons which have recent updates. In other words, it could be that recently the page triggers a newer/harsher strategy, demanding more things to be active.
I wonder if premium users can REALLY keep blocking anything, as free users need to let them sniff into our browsers and collect data.
