Transcriber not working for firefox clients

[HighwayStar]

I have up and running jitsi meet installed from docker-compose by offiicial guide based on latest stable images. I've setup vosk transcribtion and it works fine when clients using Chrome based browser, but if client using Firefox conference works overall, but not transcribtion.

When firefox client enable microphone, transcriber log looks like that

We have discovered an issue with Firefox on the latest stable release of jitsi-meet. We will push a new stable shortly and you can try with it.

Can you update to https://github.com/jitsi/docker-jitsi-meet/releases/tag/stable-9955 and see whether you reproduce it? Thank you.

Now it looks like there is regression in chrome - chat stops working on first subtitle message recieved. I've created new report in docker because didnt know where to place it, but seems related. jitsi/docker-jitsi-meet#1997

On previous releases chrome was woking fine, Firefox broken, but now Firefox Ok, chrome broken.

That was fixed now. You can use latest my nightly/unstable to try it out
