How do I solve the “PuTTY X11 proxy: No authorisation provided” error?

I am trying to run firefox on a remote server over ssh and use X11 forwarding to open the window on my laptop, but when I try to it throws the “PuTTY X11 proxy: No authorisation provided” error. I cannot find any reference to this error anywhere, and the only mention remotely close to it is here: Error Putty X11 proxy: Authorisation not recognised and none of these solutions helped at all. I can run most X11 applications, which is the reason I am bringing this here. I have tried xeyes, xclock, gedit, and netsurf, and all work completely fine. The problem is whenever I open firefox (or midori or browsh) I get this error. The full error is below:

PuTTY X11 proxy: No authorisation provided
Error: cannot open display: server:10.0

I am aware that “no authorization” has been provided to X11, but I do not know what authorization it wants or needs or on what end.
