I have to reset preferences on web sites every time I open Firefox. It also suddenly quits. I have Mac System 10.13 and the latest Firefox Version 72.0.1.

This could be due to a couple of things:

Perhaps Enhanced Tracking Protection in Firefox for desktop is preventing websites from saving the required data to Firefox. You can try setting it to Standard, if it's not already.

Another possibility is that you've set Firefox to clear your data when you close it. In the Firefox settings, under the Privacy & Security section you should check your History settings. If you are using the Use custom settings for history option you will want to check is the Clear history when Firefox closes option is enabled. If it is, click the Settings... button and more sure that you aren't clearing out the Site Preferences, Offline Website Data or Cookies, since these are the various ways that websites will save your preferences.

Hope this helps.
