You should not install addons if using Tor Browser, as they make your fingerprint unique. This is especially true of Privacy Badger, which is trained on your browsing. Both uBlock Origin and Privacy Badger are excellent addons for Firefox, but their techniques are mutually exclusive with how Tor Browser works -- they block trackers, while TBB allows them, but makes you identical to other TBB users (which you won't be if you block them).
