(Posting here for visibility and discussion.)
I have posted instructions on how to disable the screen reader mode on the wiki.
Even if you do not read that page, please read these takeaways:
- Do not enable the screen reader mode on the version of Firefox OS that shipped with your Flatfish tablet.
- The reader mode can be disabled with a volume key shortcut on more recent versions of FxOS (detailed on the wiki).
- Never disable USB Debugging (ADB access).
