i wonder if you would be willing to add support for the aws vpn client? when it is done authenticating, it leaves an authentication successful tab with the url "http://127.0.0.1:35001/".
Having a few issues saving settings in Arc Browser. This is likely related to the way Arc handles chrome.storage. Working through some debugging.
As I work through this, I added in a lot more debug logs to TabCloser that output to the console in 78a4436. These will be turned off by default but you'll be able to manually download TabCloser and turn it on yourself by changing const DEBUG = false; to const DEBUG = true;.
We'll need to verify if you can deselect a service in the options menu and if Arc will store that preference. Need to verify if you can update the seconds in the interval check and if Arc will successfully store that interval preference.
