I’m using Firefox with uBlock Origin on both android and windows. I’m finding more and more sites that are very slow to load, or won’t load at all. Yet when I open them in Chrome they work fine. I’m assuming the sites are just failing because of the privacy protection features of ff+ubo, and I’m happy enough to just avoid these shitty sites in general. But - I’m just checking to see - is this expected behaviour, might I have configuration issues?
Reset ublock origin to defaults and re configure it. That usually fixes like 99.9% of these problems.
