Any suggestions for Tor users whom a merchant redirects by https to a Bitpay invoice page? I previously followed the
instructions on the pertinent Bitpay support page, as described upthread. Otherwise, Bitpay was inaccessible to me. Neither BIP 70 nor any other Bitcoin standard is involved.
I soon will need to make a Bitcoin payment at a Bitpay-using merchant who works this way.
Did you try the Bitpay suggestion of "Vanilla Firefox over Tor"? It seems they are claiming that in your situation, you should be able to complete the captcha and see your invoice using this setup:
This captcha issue appears to be specific to the Tor browser bundle and not to Tor in general. Our team has tested and confirmed that vanilla Firefox over Tor presents the Cloudflare captcha correctly and allows users to proceed to payment.
I just tested this... and sure enough, The cloudflare captcha page is displayed in Firefox (over Tor) when the merchant redirects to "
https://www.bitpay.com/i/TXID" and it redirected to the bitpay website after completing (NOTE: tested using egifter.com as it is the only bitpay merchant I know!)
You can then use
https://decoder.bip70.org as mentioned above to convert the BIP70 URL and get the address and bitcoin amount.
LATE EDIT: In actual fact, you could probably just ignore the whole redirect to bitpay.com and simply take the TXID from the URL and put it straight into the decoder as:
bitcoin:?r=https://bitpay.com/i/TXID_GOES_HERE
