Some login pages get 404 or 403 - very well in other browsers

Hiya', people!

Well, I did some research to find answers before deciding to ask my question - just to put it out there. Found a few things that seemed on the surface to be bound, but then, as I read the posts, determined that they were not. I therefore ask my own question:

I have several websites that I cannot log in to Firefox, but CAN connect perfectly fine in other browsers. (As a web designer, I have all the major browsers installed on my system.) For example, the login page for my Craig list goes directly to their "404" page My College's statistical information system login goes directly to their "403 - Forbidden" page (note the difference returned error). A couple of others, as well. NONE of these pages are my favorites.

I tried "power refresh" each page (Ctrl + F5). No dice.
I tried to delete my history and cookies. No dice.
I tried to remove it completely with iObit uninstaller of Firefox (but has NOT removed the my profile folder because I wasn't ready to do it again) and then re-install. No dice.
I tried to disable all add-ons, plug-ins and extensions. No dice.
I tried to delete the file "cookies.sqlite" (but could not find a file ' cookies.sqlite - journal ", as described in the troubleshooting section). No dice.

So... until I delete my profile folder, shred Firefox completely from my computer and go to a new installation, any ideas? If this is not the case, in my history or cookies - or in the file cookies.sqlite - WHERE on my system these cached pages and WHY are they not allow me to access it through Firefox?

Thanks for any help there ' All can provide!
