How does anyone broadcast bitcoin multisig transactions in tails?

Does anyone know how to broadcast multi-sig transactions in tails? I'm trying to do so and it seems that the tor browser somehow blocks coinb.in from doing so on the "#sign" page. The "unsafe browser" can broadcast on coinb.in, however.
Is there an alternative to coinb.in? Tails seems to fuss with it. In any event, couldn't the electrum client simply sign a multi-sig transaction and then broadcast it? Why isn't everyone just using that?

Bitcoin Cash (BCH) just had an upgrade that added Schnorr signatures. It helps with scale-ability and will make a huge difference for multisig transaction size.

when multisig is added, will it be possible to do atomic cross chain transactions with Bitcoin & Monero?

https://en.bitcoin.it/wiki/Atomic_cross-chain_trading#Algorithm
I believe the issue that comesup is that monero's lock time and bitcoins nLockTime work differently and this affects the algorithm linked above.
"A special transaction where the recipient can only spend the funds after a future date, as set by the sender.
Unlock time allows you to send a transaction to someone, such that they can not spend it until after a certain number of blocks, or until a certain time.
Note that this works differently than Bitcoin's nLockTime, in which the transaction is not valid until the given time." -- https://getmonero.org/knowledge-base/moneropedia/unlocktime
So I think a new scheme likely has to be developed as Monero unlocktime does not allow you to return the coins after a certain peroid.
I am not sure how to do it and it might not even be possible in a way that is zero risk for everyone.
As I am reviving Bitwasp and integrating it with Monero I thought it might be good to explore atomic cross chain transactions with Bitcoin since Bitwasp already works with and does multisig bitcoin transactions.
It would be very good for Monero if I were able to easily add some sort of atomic cross chain transaction feature that allowed people to buy monero using bitcoin and all of it's clones (ETH, Dash, etc) in a fully anonymous and trustless manner.
Being able to do so would allow for more capital to flow into/out of Monero and increase liquidity.

How to use multisig for a safe bitcoin transaction without involving a 3rd party

In order to create an escrow that doesnt require a third party , and insure that nobody get scammed in a bitcoin transaction, how about the following protocol:
Alice order a phone to Bob for 1 BTC. they create a multisig with 2 out of 2 signatures required (A+B) they create and sign a transaction that put 2 BTC from Alice and 1 BTC from Bob into that address They create a transaction to send 2 btc for Bob and 1 btc for Alice when Alice gets the phone, she signs the transaction and send the signature to Bob, Bob signs it as well and get the Tx broadcasted.
This way any scam will result in the loss of the scammer's BTC:
If Alice lies that she hasn't got the phone, she is losing 2 BTC for 1 phone, assuming the phone's value is 1 BTC she lost 1 BTC of value in the process (Honest Bob is losing 1BTC+1 phone = 2BTC of value)
If Bob is a scammer and doesn't send anything, he is losing 1BTC (And honest Alice is losing 2 BTC)
This would protect against all scams designed to generate profit for the scammer. And defeat all scams aimed at generating a loss for the victim at no cost.
