I'm giving 5 stars solely because it was made by EFF, and it does seem to deliver on what it promises, and it is a damn important thing to have, For me, unfortunately, I had to uninstall , because whenever I clicked on the icon, my browser would freeze, and I would get unresponsive script. Firefox always managed to recover gracefully, but still an inconvenience. Never had a similar problem while using ABP, what it seems to be based on, but I've since moved to uBlock Origin which also works flawlessly. Maybe my laptop is too outdated.for privacy badger...
