I tried everything that you describe on your description page about this addon. But it doesn't do anything. Neither it shows any popup bubble when I highlight the paragraph text. I tried both the HTML5 and Google. Nothing happens. I am going to uninstall it. waste of time.
You should have an addon icon on the addons bar so we can see it and activate it. we don't see any addon. Like a ghost is hidden?

Unfortunately doesn't do anything. Highlight text, press button and progress indicator keeps spinning...

Doesn't work, highlighted some text, clicked button, nothing happens

Clicking the speaker just hangs at loading animation. Also, I can't find any evidence that "morni colhkher" is a real person. The homepage consists of mostly filler text. It is hosted on "MyBrowserAddon" which is faceless and nameless, and has no company info and no login- you have to use a contact form to "start an open-source project"

does notz work properly, when the icon appears after highlighting the text, and clicking on the icon, it keeps on showing as if its loading (circular motion) but nothing happens...

I can't recall ever using it much - BUT in the Linux eco system (Debian based), it keeps on adding more and more and more "speech dispatcher" streams to the Audio channel / sound mixer.

And like most frustrating things - there is no way to stop this process of every time open another webpage with readable contents, it opens another audio stream / channel.

And they do not seem to close down when I shut down the web pages...

So I'd say this is not actually a fault, as a for instance if I were to open 3 or 4 sets of the VLC media player, I'd get exactly the same thing.

I'd rather see it as a single program, with branches into the websites, instead of multiples of the same program, going into the different wesites...

Doesn't work

Doesn't work at all.

Does not work.

The voice is horrible. It sounds like a worsened version of Stephen Hawking's computer voice. 1 Star

Does nothing and can't get to work.

Literally does nothing

Just doesn't work I'm on Firefox 57.0 on windows 10 app just flat out doesn't do shit.

Does not recognize language correctly, and there's no way to set it manually.

Głos - przynajmniej w języku polskim, inne mnie nie interesowały - jest sztuczny. Generowany jak z komputerów z głośnika systemowego, robotyczny. Nie polecam.
