Really horrible. Voice sounds are really bad, most of them are "premium" or require special access.

decent add-on, but it no longer reads after right clicking - which sucks. So I uninstalled. Very disappointed.

simple and it does the job, thats worth 4 stars.

One complaint: cant adjust its focused words outside of selecting any given paragraph. I hope to see it refined for selecting an individual sentence, or perhaps a scrubbing system.

Unable to get it working on Android.

Sorry but the audio sounded like ghost from Event Horizon shrouded in death noises from Event Horizon. Deleted immediately, thanks for the nightmares.

sadly no Brazillian portuguese on free version

Gracias por tu aporte, en nombre de los que usamos GNU/Linux te lo agradecemos.

Couldn't find less than one star. Sorry honest as I could be

Tốt

Thank you for this! so much better than the stock windows voices.(Using Latest Windows 10 64bit Desktop W/ Regular Firefox Install). Have not tried Android Verison. Used it 4 times just tonight!

anda muy bien, gracias

Android version. Couldn't get it to work. Fresh Firefox install from Play Store, no other add-ons installed. Selected it in the add-ons section of the Firefox menu and am informed that it needs more permissions to talk to Google. I click the grant button and nothing happens. I click the permissions link and nothing happens. Spent an hour researching and trying different things, nothing works. I'm removing it, likely permanently.

Works on PC and Firefox Nightly on Android. Thank you!
