[Solution] YouTube 400 Bad Request: VISITOR_INFO1_LIVE
Have you ever see the following error message when you are trying to access YouTube using Firefox?
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.
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:
- Locate your Firefox profile folder (how?)
- Delete cookies.sqlite and cookies.txt
It works well for me.
