it wasn't when I tried it a year or so back. It told me to report bugs to Discord, but Discord crashed immediately in Orion. I think it turned out to be uBlock Origin or something, but still was a very frustrating experience. 1Password also didn't work correctly.

Obviously they can't control extensions, but if popular extensions break your browser, and you don't offer a good native replacement, it's a bit of a no-go.

This was a year or so ago, so maybe it's better now.
