Text-to-speech doesn't work in TBB since El Capitan
At Tor.SE there is a question regarding text-to-speech and Tor Browser. The user is dyslexic and recently upgraded to El Capitan (10.11.6). Since then the text-to-speech software stopped working with TBB. The software reads the entire webpage instead of the text the user had selected. It worked in previous version of Moc OS X and it also does work in Firefox and Safari. So it seems to be a TBB related bug.
Do you need more information? Can you help to fix this bug?
