Can’t login after FF browser update My Firefox has just updated to version 17.1. When I try and login I get this message:


  Access denied
  You are not authorized to access this page.


The URL does however recognize my account as it contains /users/myusername

I can log in fine in older versions of Firefox, and Internet Explorer. I however get the same problem in Safari version 4 Public Beta (528.16).

Does anyone know a fix for this? I have tried rebuilding permissions but it didn't help. 

I am running Drupal 6.
A similar situation was encountered by a user who reported that clearing his browser cookies solved the problem.
