I can access most typical sites, such as GoGoDuck, checktorproject, and hiddenwiki, but I attempted(multiple times) to access the BB Compendium, Libera Tor, and other sites having to do with that sort of information, and kept getting a response saying:
"Firefox can't establish a connection to the server at *****.onion The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Tor Browser is permitted to access the Web."
My firewall allows Tor to access the internet, I can access multiple stable sites, and I've been on the aforementioned sites before multiple times
