It will let me play all my other facebook games but not Pioneer Trail. I was on it early today with no problems but now it comes up with the message "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." Why is it doing that?

What happens if you try this in another browser, like Internet Explorer or Chrome?

Still nothing. I have to go to work. I wasted 5 hours trying to deal with this. I just want to play my game. I just don't understand how it will let me load every game but this one. I hope it works the next time I'm able to get on the computer.

I notice you are using a very old version of Firefox. It might be a good idea to update it. You can follow these basic steps to do so, but they might need to be adjusted for your setup. Also keep in mind that this can take some time.

It's not my computer cause I've tried getting on a couple of friends' computers and it's doing the same thing. This is really starting to piss me off. I only have a couple days I can play my game and I can't.

You can update Firefox by going to the Terminal or a similar program on your Ubuntu computer and do these two commands.

  1. sudo apt-get update
  2. sudo apt-get install firefox

or use the Update Manager and install any other updates you may need

First of all how can it be my computer if I can't load the game on friends' computers either. Second why am I not having any problems with any other facebook games?

Did you make sure that they deleted all Facebook cookies?
