This will get bumped to a 5 when you can tell us how to fix the context menu option from disappearing.

For the meantime, here are the short cut keys to do the same things:
To Play - Alt-P
To Stop - Alt-O
Go Forward - Alt-Period or "Alt-."
To Rewind - Alt-Comma or "Alt,"

If you should forget Alt-P - Click the button in the toolbar that looks like a megaphone, if it's playing, hit the stop button. Then click the gear button next to the play button. A larger "Options" box will open, at the top you will see "Edit shortcut keys" that will open a new tab with the short cut keys listed. Using Alt-P will speak what you highlighted. If you don't highlight anything, it reads the whole page I believe.

Oh and some might not know but the little gear button is also where you change the reading voice. I like the Amazon ones.

Hope this helps you folks out while we wait for the fix. Actually Alt-P might be easier to use than the context menu. If they made this option clearer, most people probably wouldn't care and again, I would bump my rating up to a 5, for the clarity.

With the recent update it become completely useless.

The TTS (multi-language tts) worked well enough but stopped reading PDFs as FF was updated and the developer perhaps gave up. This add-on reads my PDFs beautifully and all the controls work perfectly. Thank you. Thank you.

Great usability. Amazon voice "Kimberly" sounds the best to me. Very listenable.

Yeah i like how it highlights. This Text to speech FF addon is awesome!!! Yay!

It does the job, however, the voice is one of those old-school 1980s movies robot voices. Still use it just wish the voice was a little different. Sometimes it's hard to understand the voice for technical Words which is the reason I got it but that's okay.

It works well but it gets stuck on things. For example if its italics then it reads it over and over. Same thin with numbers it will reread it over and over.

This is an awesome addon and is free/libre software

Fantastic.

So good! highly recommended!

Simple to use, just select your webpage text (including web-based emails), right click and click on "read aloud". Excellent choices of voices in the settings as well. A great and useful tool, definitely a keeper! Many thanks!

App simples! Voz bem sintetezida!

Works well. I use Alex and slowed the natural speed down a bit and it's perfect! Please keep it up!

5 stars for ease of use. 2 stars for A.I. voice. No choices for voice.
