I've been using the addon since it was released but after the latest update, I got this message:

"One of your browser settings prevents the “Alternate Player for Twitch.tv” extension from working. To fix it, open the tab with the address about:config. On the page, paste privacy.firstparty.isolate into the search field. The current status of this setting will appear below. Double-click it to change the value to “false”."

I know I can change this setting but I don't want to. I see no reason why this is now required to use the addon. Will it be fixed any time soon?

I love this addon and I use it completely in place of twitch's player. I was wondering if there was a way to remove the black bars when in fullscreen for a fully immersive experience.

Can confirm for dev that Twitch Drops work perfectly fine.

this addon is great but it's stopped working on Firefox 70.0
any updates coming?

Thank you for this! Any way you can get it to work with VODs as well?

I had some issues with Twitch where the video froze but the stream continues when my computer has a big workload. This extension fixed all of that and everything loads faster! Now that I'm used to the UI, I don't think I can ever go back!

I was amazed by how much better my Twitch experience got with this player. My internet is OK but both the official player and streamlink lag constantly, this one goes 1080p60 95% of the time without any lags. WP!

video to stop running after opening any channel and moving the mouse, only the audio continues to run.
I deactivated all addons leaving only the Alternate Player for Twitch.tv, anyway, the video stops working.

Thank you, it's working now.
