Ever since I upgraded to this version of Firefox (57.0.2 (64-bit)) none of my web pages recognize the browser nor do they remember it even after instructions.
Ever since upgrading to the Quantum version of Firefox, my usual web sites do not recognize the browser nor to they remember it even when instructed to do so. This did not happen with previous versions of Firefox. When will this be fixed????

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. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) 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/
