No screen sharing icon in firefox

Hi guys,

today I installed Jitsi-Meet in docker (quick install way) just to try if screen sharing is possible. Unfortunately I can’t see the screen sharing icon like I see when I go to

Reading some of the posts in the forum my understanding is that there is no need for an installation of a browser extension because Chrome and Firefox (don’t know about other browsers) already implemented “getDisplayMedia”.

For Google Chrome an extension is still needed, you need one for your deployment.

So I expected the screen sharing working out of the box.
Btw. I did not execute the let’s encrypt scripts, so when I go to my local jitsi page, I accept the unsinged certificate and proceed to the page. I hope the certificates don’t matter here.
Are there some configurations I have to set to enable screen sharing?
I tried setting “desktopSharingFirefoxDisabled: false,” and calling
./prosody restart &&
./jitsi-videobridge restart &&
./jicofo restart &&
./nginx restart
but that did not help.
Another thing I is that after about 36 seconds a reconnection popup is shown.

You have been disconnected.
You may want to check your network connection. Reconnecting in …

Wondering if this is also a problem (guess that’s because I’m the only person in the conference??)


firefox: 68.5.0
jitsi-meet 1.0.4275-1
jitsi-meet-prosody 1.0.3881-1
jitsi-meet-turnserver 1.0.3881-1
jitsi-meet-web 1.0.3881-1
jitsi-meet-web-config 1.0.3881-1
jitsi-videobridge 1132-1

Tried the stable version but still there is no screen sharing (desktop) icon :frowning:
Can someone tell me what has to be done to make the screen sharing icon/button show up?

So I installed jitsi-meet on a public server (so I can make sure docker is not the problem). Now I can open two firefox windows in private mode and start from one window the conference and join the conference from the other window. I can chat from both windows but screen sharing does not work.

In the firefox console I’ve seen this error (replaced ip address with MYSERVERIPHERE):

I compared my config with the one from “” and here are some things I was wondering about:

=> I don’t have the enty: Component “

nginx config
listen 4444 ssl http2;
listen [::]:4444 ssl http2;
=> shouldn’t that be 443?

=> I have: proxy_set_header Host $http_host;
=> instead of: proxy_set_header Host $host;
