It worked fantastic for a long time, but a few days ago, something changed. I can no longer visit websites that are setup in a certain way, unless i turn off the Extension. X for example, or the tracking website for my local package delivery. They will load partially or give me a message saying the website cant currently be displayed and when i turn the extension off, it works per normal. Very odd. I will stick with it for now but if i end up having to whitelist most of the websites i use, i might have to change.

edit: I found out, by trial and error, its the Ultimate Privacy Filter thats the issue. If i deactivate it, i can load all pages in question, if i activate it, i cant.
