HaloMods "Classic" Read-only Archive

For some reason Firefox will not let me log into Halomods forums, both this and the files forum. I put in my user name and password and click login, and it sends me to the forum main page, but still logged out. I do it again, and this time click the "remember me" box. Still won't login.

I don't have this problem with IE (which is how I'm posting right now). Is it a problem on my end? Or is it a bug with the forums?

EDIT: Never mind. Talked to someone else and I cleared my cookies and cache. It worked. Lockplzkthxbye.
