I share the same view as VANX has done. It does not work on Ubuntu / Firefox.
Also, it does not offer Persian voices.

I have to rate 1 start.. I'm runing Ubuntu and FireFox.. It did not work.. Not seeing what I can do differently.. My mic works.. I toggled on and off.. tried in different typing areas and it does zero.. yep.. 1 star..

i did everything they said to do but when i click set up stubs and then click downloads, it starts then when its done downloading to opens a new tab and nothing happens i hope i didn't just download a virus 😒

absolutely fucking glorious. saves so much time. thanks for this.

Great plugin! Never have to touch my keyboard again
