Hello All,

I've been having random firefox customization resets. I'm calling it random because I can't spot a patten for when it happens. Its been happening for months. Restarting firefox and this pc doesn't seem to cause it. But shutting down for a longer period of time seems like its more likley to happen, I'm talking 7+ hours.

Whats getting reset

  • Welcome to Firefox tab opens
  • Firefox Privacy Notice tab opens
  • Theme is reset but is still marked as selected
  • Addons are reset but still installed/enabled
  • Tab/Home Options reset
  • Layout of file menu reset (downloads,home,reload,addons,ect)

What I've tried

  • Firefox refresh (A week ago, I loaded back the same addons I had before, not sure if they could be doing this)
  • Check the prefs.js is not locked/readonly
  • I don't have a user.js
