Frederic, have you forgotten about me so soon? đż Letâs move this to accessibility-...@group.apple.com <mailto:accessibility-...@group.apple.com>
Short answer is VoiceOver probably needs to white list firefox as a âweb browserâ. What is the bundle id being used? We are checking if the app is org.mozilla.firefox or org.mozilla.nightly and treating that as a web-browser Also you will need to post AXLoadComplete when the page is done loading > On Oct 1, 2015, at 5:00 PM, Darin Adler <da...@apple.com> wrote: > > >> On Oct 1, 2015, at 4:10 PM, FrĂ©dĂ©ric WANG <fred.w...@free.fr> wrote: >> >> Hi, >> >> When Safari has finished loading a page, VoiceOver plays an ascending >> three tone sound effect, selects the web document and starts reading the >> page.
