On one laptop I use frequently I usually lose my sync settings between Firefox sessions. I have to re-login to Firefox, log out, then log back in - and they recover. There must be something (spyware monitor?) doing it because it doesn't happen on other laptops or desktops I use. Any suggestions (it's surmountable but annoying).

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
