There is no option in the context menu to select text on the page and read directly.

Also, the voice is too robotic, take an example from MS Edge and their reader and TTS
And one more thing, TTS does not support my language :((

Stop bullshitting people with your robot voices from Microsoft in your TTS extension. This extension is simply the last shit because these Microsoft robot voices are unbearable.

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 ?

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."

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).

Does not work. Cannot get tts to start.

Horrível! A voz é masculina e robótica! Não possui controle de velocidade da voz.

Not criticising _intended_ functionality.
I haven't used it much - I tend to use Read-Aloud, but it breaks the ability to change font in Gmail: select text, click to choose font, text is unselected, so whatever font is chosen is not applied. Disable this add-on, and I can change font in Gmail.
FINALLY found out why! Bye!

Voz robotizada e fala pausada . Português ruim.
