Screen reader does not read contents on first (starting) slide
I'm building a module that needs to be fully accessible. It's a fairly basic and linear module, with a menu on the top (the first items to be read). I have set the screen reader visibility on required elements on the slides, as well as Alt Text for some. I used 2 screen readers: NVDA and Thunder Storm.
Here are my issues:
- The contents are not read at all in Chrome.
- The contents of my first (starting) slide are not read in Firefox. As soon as I go to another slide (either from menu or next button), the contents are read correctly. When I go back to the first first slide, the contents are ten read correctly also.
- IE reads all contents correctly right on the first slide (with the first tab)
Is there anything I can do to fix the Firefox issue?
