Added try/catch and updated awaits for async methods in regards to sign
in attempts. This appears to resolve some race conditions with nos2x
extension. More testing to be performed.
I did this because they are 2 separate concerns and I have diverged
so far from the original repo. I didn't start a new repo because it
contains valuable history of all the people who contributed to it.
Additionally if there is an issue with this we can revert, but I
rather not. Forks are forks.
