Ce module est excellent sur Edge : les voix sont de grande qualité [Microsoft --- Online (Natural)].
Ce n'est malheureusement pas le cas sur Firefox, mon navigateur par défaut. Les voix utilisées sont médiocres et surannées [Microsoft --- French/English etc...].
Pourquoi ne pas faire pour Firefox ce que vous faites si bien pour Edge ?

The highlighting is nice, something that I couldn't find in other extensions, but the voices are NOT natural (like the MS Edge TTS extension), they're just the classic robotic voices included in the OS.

Doesnt work on local pdf files even if i grant access

i prefer it to voice aloud reader, because it's easier to pause. It has many languages, including mine, which I'm thankful for

Funciona ótimo ele lê meus textos em voz

Just dumb. opens a separate window instead of reading the text in the browser

In about:config you can only choose 'true' or 'false'.
There is no 'toggle'.
The highlighting works, but there is no sound/voice.

"Note 2: HTML5 TTS API is still a work in progress and may encounter crashes or errors. If the API is not active in your browser, please go to "about:config" page and search for "webspeech" keyword. Once you find "media.webspeech.synth.enables" item, right-click on it and click - Toggle - to enable it."

VERY NICE !! ONLY I WISH IT HAD AN SPEED CONTROL & GIRL VOICE :D

Terrible UX - opening a separate window for a seemingly simple function defeats the whole purpose of an addon. Waste of 5 mins of my life (including 2 mins reviewing this).

Russian language - not working at all
