Profile data can be removed or not recorded in several ways;

  • 1) Running Firefox in Private Mode (nothing is recorded)
  • 2) Privacy settings; (In the address bar, type about:preferences#privacy<enter>)
  • 3) Many disk cleaners and anti-virus type programs can remove data from browsers
    Open their settings and have them leave the browsers alone.
  • 4) Mal-ware.

I normally run the browser in normal mode, after a fresh install windows 10 3 month ago, i delayed activate firefox sync. it is possible that since this the error is available.but i cannot say this for sure 100%. i do not use disk cleaners, there was no malware detected on the system. also after a scan with with win defender no virusses detected. so unfortunately the 4 points didnt help.

Some anti-virus don't detect malware.

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 free to use malware scanners. Each works differently. If one program misses something, another may pick it up.
