[Solution] YouTube 400 Bad Request: VISITOR_INFO1_LIVE

YouTube iconHave you ever see the following error message when you are trying to access YouTube using Firefox?

It used to happen to me. Then after a while, it’s gone, and now it’s back at a higher frequency. I have to clear the cookies every single day to do away with the error message.

After a bit of Googling, it turns out that there are quite a lot of other Firefox users with the same problem. If you are one of them, try the following steps to see if it helps:

  1. Locate your Firefox profile folder (how?)
  2. Delete cookies.sqlite and cookies.txt

It works well for me.
