Everytime I close firefox and then reopen it I have to sign in again all my search history is gone. I have tried all the fixes I can find online and nothing has fixed it. Unfortunately I will have to go back to Chrome unless I can get it sorted.

What's your computer system and Firefox version?

Sync works in the background. As long as the browser is open long enough, the data is synced.

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Options/Preferences -> Privacy & Security
    Firefox will: "Use custom settings for history"
  • remove checkmark: [ ] "Always use Private Browsing mode"

Thanks for the reply but "Always use Private Browsing mode" is definitely not checked.

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.

Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.

At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.
