Fakespot completely broke Firefox for me. As soon as I installed it, every single page stopped loading—just an endless loading screen, no matter what site I tried. Thought it might be my connection, but other browsers on the same machine worked fine. Uninstalled Fakespot, and Firefox was instantly back to normal. Hard to see how it wasn’t the addon causing the issue.

Unless they fix whatever’s going on here, I can’t recommend it at all.
