api.SpeechSynthesis - pause() action is not working in Mozilla Firefox 130.0 under Ubuntu 22.04 and 24.04

[ACSantanaB]

What type of issue is this?

Browser bug (a bug with a feature that may impact site compatibility)

What information was incorrect, unhelpful, or incomplete?

The browser compatibility table mentions that these features work in Firefox.

What browsers does this problem apply to, if applicable?

Firefox

What did you expect to see?

When the API is vocalizing a text and you try to pause the process, in Mozilla Firefox under an environment with Ubuntu operating system, the pause action is not working, the cancel action does work, but the pause action does not, so apparently there is a problem in pausing the queue.
Also the resume action could be affected? We don't know since the pause action doesn't work and we don't know if we can resume a paused audio.

Did you test this? If so, how?

Current confg:

• Toshiba satellite with Ubuntu 24.04 LTS / x86_64
• Amazon workspace with Ubuntu 22.04 LTS / x86_64

Running the Mozilla Firefox browser in its latest version (130.0), open the developer tools console, and execute the following process:

const synth = window.speechSynthesis;

const utterThis = new SpeechSynthesisUtterance('Its the start of the school year, and thus the start of a fresh round of discourse on generative AIs new role in schools. In the space of about three years, essays have gone from a mainstay of classroom education everywhere');

synth.speak(utterThis);

wait one second before pausing

synth.pause();

the audio should pause but it is not pausing.
