this is really to report what occurred this morning.

since the update to v 17 Firefox would not run d/loaded the new version twice (uninstalling between) but to no avail - the program would not open although Task Manager shows the process running.

have re-installed v 15 so I have a browser.

lack of a way to report such problems is a weakness which needs addressing

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
