I hope these answers can help:

1. I used firefox on a desktop.
2. I only checked Steemit, cause I havent set up a Golos account. I set my private Posting Key of my steemit account in the settings tho.
3. Yea I just posted it now: https://steemit.com/bitshares/@lunedio/cryptofresh-down-here-are-all-alternative-bitshares-explorers
