Comment 0 for bug 1987979

I just noticed that the narrator feature, which reads articles out load with TTS in Firefox reading view stopped working after upgrading to 22.04. Another user reported the same problem on ask Ubuntu:

Also, if you have no clue what this is about: https://askubuntu.com/questions/953509/how-can-i-change-the-voice-used-by-firefox-reader-view-narrator-in-ubuntu

$ lsb_release -rd
Description: Ubuntu 22.04.1 LTS

2) Firefox is a snap now, but I guess for the feature to work it needs to detect TTS which is packaged as deb.
