This question already has an answer here:
I can't use Tor. I'm using an ISP via WiFi in my local town and cannot access some of my favorite .onion addresses. My usual method is that I have profiles in Firefox which allow me to choose to use Firefox incognito before it even begins. I hit alt+F2 and type
torify firefox. Then I choose the incognito profile I've setup and then head on over to a .onion address. With this new WiFi network, it appears that nothing is getting through to the Tor network.
