Suggest Uninstall and reinstall Version 56.0.2 with the Full Version Installer. https://www.mozilla.org/firefox/all/

To run the SFC command use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). Type "SFC /SCANNOW" (without quotes or copy/paste) and press Enter.

Run the Windows Deployment Image Servicing and Management (DISM) and System File Checker (SFC) tools as Administrator. The DISM and SFC tools scan the integrity of the Windows image and all protected system files replaces corrupted, damaged and incorrect versions.

Please let us know if this solved your issue or if need further assistance.
I don't know what the Windows 10 Troubleshooter does, but if it says that Firefox is not compatible with Windows 10, perhaps there is a problem with the program files because Firefox definitely is compatible with Windows 10.
Hopefully the above system maintenance tips will be helpful. Here's one other thing to consider:
One of the main effects of the Firefox 56.0.1 update was to migrate 64-bit Windows users from the traditional 32-bit version of Firefox to the 64-bit version. We've received a number of puzzling reports of Firefox either not starting (probably due to incompatibilities with 64-bit drivers that Firefox expects/requires) or not loading any pages after this migration.
One user discovered that Windows was silently killing Firefox at startup and recording it in the Windows event logs (you can view event logs using the Event Viewer). Based on one of the reports in the log, we were able to trace that to an out-of-date Logitech camera driver, of all things. Two other users reported that uninstalling the Logitech camera resolved their problem as well.

Do you want some assistance in looking at event logs, or do you have such a camera?
If the investigation doesn't yield any solutions, it is worth trying a return to 32-bit Firefox.
While normally this kind of change is seamless -- the installer detects your existing data and preserves everything -- you might want to make a backup "just in case."

Note: If you decide to try 64-bit Firefox on the same system at some point in the future, see: How to switch from 32-bit to 64-bit Firefox.
