What could be clearing Firefox Cache?
I'm accessing a remote desktop Windows server. I have installed Firefox Portable. When I login to the site I reach two-factor authentication. I've authenticated it manually and ticked the box 'Don't ask for codes on this device'.
Each time I relaunch Firefox it works without having to reauthenticate, but each time I close the remote connection and reconnect, the Firefox cache appears to have cleared and I have to go through 2 factor authentication again.
Have you any idea why the cache would be clearing? I sometimes run CCleaner manually but even when I do that, I can still login without 2-factor, so I don't think it is ccleaner causing the problem. I think it is something to do with reconnecting to the server.

I don't think it's a cache problem; more likely it's a deleted cookie.
Is the remote system's public IP address stable from one login to the next? Sites that require two-step authentication may invalidate an existing cookie if the IP address does not match the session during which the cookie was set. (This protects against impersonation on another network using stolen cookies.)
Thanks that makes sense but I don't think the public IP address changes.
I use an IP address to login and that doesn't change. I've checked whatsmyip.org and it matches what I login with.
Okay, is there any reason that cookies might be getting cleared in your remote Firefox? You mentioned CCleaner. Is it set to purge any browser data at system startup?
Oh wait, you said Firefox Portable. CCleaner probably doesn't even know about it. Could you ask on their forums whether this is a known issue?
OK thank you for your help. I've posted the question over there.
