Hello, Chris. I have downloaded uBlock Origin for Firefox and it works like
a charm on hotmail outlook. However it seems to prevent me from using some
features of another website I use quite often (full screen slideshow on
yourshot.nationalgeographic.com). I tried adding this website to the
whitelist but it still blocks the feature. I am not very adept at playing
with the various toggles, but will try.
You can disable uBlock for yourshot.nationalgeographic.com by clicking the big blue Power button when you're at that site, see screenshot. But this also depends on the filter lists you're using and whether you've enabled element hiding (cosmetic filtering).
