They decided to drop support for firefox.

Worthless piece of garbage. Doesn't work at all

leider klappt prime video überhaupt nicht... netflix funktioniert hier aber ohne probleme... hat noch wer das selbe problem? bei meinen freunden funktioniert es mir prime video in firefox auch nicht... mit einem update ist wohl nicht zu rechner weil das letzte update über 1 jahr alt ist... und das bereits seit mind 4 monaten nicht mehr funktioniert

works for youtube well

very useful :D

Does not work with HBO Max at all. The total video playtime length is different between users so it's totally de-synced. Controls are also very finicky and don't work for one of the people most of the time.

Nice extension but only works on Netflix

Plain and simple will not work after an hour of trying. A valuable hour in a long distance relationship wasted with trying to troubleshoot, wit no results.

I strongly recommend against using this app. This app massively slows down YouTube even after uninstalling. This has occurred to me on multiple occasions. Resolving it requires creating a new FireFox profile. I will not be using this app on my main browser anymore.

Right now, it does not work on Amazon Prime. It gets restarting and restarting the video, again and again...
Pls fix.

No começo funcionava muito bem. Eu e meus amigos amávamos e era muito simples de usar. Daí um dia, do nada, começou a quebrar sincronia dos vídeos, pular parte, quando uma pessoa da pausa, da play para outra. MUITO ESTRESSANTE a ponto de a gente desistir.

very good

Works flawlessly for Netflix and Disney+

When it works it's great. It's rarely great.

The good news is that both my wife and I started a free trial that automatically converted to individual one-year subscriptions, so now we are both paid up for a year of something that rarely connects us as we want to connect.

I have tried installing the extension on three browsers, with with various errors on each (Safari, Chrome and Firefox).

As I travel for business a lot, I was hoping TeleParty would allow us to maintain some semblance of normalcy in our relationship, but instead, it has introduced a toxicity of having an alcoholic friend couchsurfing in our home where we can't do the things we want to do together.

Thanks, Teleparty, and enjoy our $120 dollars until next year. We will keep trying, but eventually, you are going to have to get off of our couch.
