@phoneboy Never. I find I have to add a few minutes to the start of most meetings lately to find a browser that will work with someone's boutique conferencing choice du jour and configure it to use the right audio input and output.
Google Hangouts has also got right annoying now that Firefox dropped npapi plugin support but Google decided to opt for "kinda WebRTC, not quite, anyway, it works in Chrome, y'know?" as the sole alternative. So now I need to spawn a new browser just to do phone calls.
