running someone's credit card using proxy

so today I did something stupid.

I usually have firefox set up to go through a proxy. Firefox is not my normal browser and I only use it if I need to hide my ip for some reason.

so today I was in a hurry to run someone's credit card through my processor. the only window I had open was firefox and since I was in a hurry, I just used that....I didn't realize it was going through a proxy.

card took longer than usual to verify, I was like "WTF? why is it taking so long....maybe because it's amex...oh well..."

Then a few minutes later, I realized what I had done. I already changed my password. Is there anything else I should worry about?

Why does it matter?

I would say it probably depends on where the proxy is hosted and by who.
Took longer because you went through the proxy and ist not a direct connection but you should be safe especially since you already changed your pass.

If your connection was secure (via https) between your client (Firefox) and the credit card processor website (whatever) your proxy (which is not web based) will not be a threat.
If you have connected your proxy website first (web based), then entered your credit card processor website and credit card numbers then your proxy may be a threat.

I am not sure what you mean? what do you mean by "web based"?

Depends. Should not matter in my opinion because all of the gateways use https, so your requests can't be eavesdropped. Still, i know some people who can tear apart SSL. But because you changed your pass, you should be OK.

You should be ok.
