Two weeks ago, I apparently made the mistake of deleting my cache and all cookies. At the same time, I also selected the "I do not want to be tracked" option available in Firefox's security options. After realizing that I could no longer access my iGoogle homepage, I put all of my security options back to the same status as they had originally been. Unfortunately, I am still unable to log in to anything Google since that day. I use Firefox 12.0. I am able to login to Google using IE (thankfully, but unhappily). I have tried checking my anti-virus settings, my cookies, and cache settings as many users have suggested, but to no avail -- I still cannot login to Google services (including iGoogle) using Firefox.
I would appreciate any help or suggestions that would allow me to use my favourite browser and the Google services that have become a solid part of my every day life.
