It works only on browser based on webkit (Chrome, Safari…), so unfortunately for the moment, DoDoc is not working on Firefox.
We have tested Do.Doc on :
- Mac OSX system on Chrome – works fine
- Linux on Chromium – works fine
- Windows 7 on Chrome — works fine
- Raspberry Pi 2 on Chromium — we are still working on it
- Raspberry Pi 2 on IceWeasel — we are still working on it
