So deleted update to Quantum 57.0 for the fifth time because "incompatible" and won't play my live channel or On Demand programs on tv.xfinity.com; but now, I can no longer play on 56.0 either!

This is ridiculous!

Note: ver 56.0.2 is no longer receiving any updates and is now listed as a Security Risk. Use 52.4.0 ESR or return to 57+ and ask questions before jump to action. This usually leads to more work for both sides to uncover the issue. Note jumping back and forth is sure to screw up your Profile with all your info in it as not compatible.

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0.2 with a Full Version Installer https://www.mozilla.org/firefox/all/
