Cannot access Tbird on PC, but have done so using Outlook; and Tbird Outlook & Samsung mail on mobile. Gmail: some new messages and those quite old are accessible. See Screenshot. iinet: nothing accessible. See Screenshot. The password used to access on webmail works there but is not working in Tbird on thePC. Three technicians have attempted and myself have attempted to rectify. A primary password was used earlier, this has been unsuccessfully tried. It isn't required now. I fear this may be the problem but don't know how to rectify.
