Since I started using firefox all my add ons get uninstalled for no reason from time to time. It's like the browser decides to wipe them all out and I have to reinstall them again, one by one. I tried creating an account and syncing, but the problem persists. And it happens on both my 2 computers.

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .

Are these all add-ons, some of them? If some, are they the same ones?


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.
