Hello jhep3304 ,

I would like to recommend you to reset your FF browser cuz i think your issue is from Update from old Version of newer !

before you reset your Browser please do back-up from your Data and History(s) = Create an Synce-Account

After Synchronisation you able to reset your Browser

writte on Search-Bar (above of your Browser) => about:support

here you can reset your Browser and after reseting you should log in with your Synce-Account on your Brwoser to restore your Historis

I hope i could help youabout your Issue

Thanks for using Firefox

Thanks. I think I resolved the problem as follows: I opened: Tools-Options-Privacy and under History, I changed to "Remember History". I then closed Firefox and re-started. At that point, the History section tabs were fully restored. I then went back to:Tools-Options-Privacy and under History changed to "Use Custom Settings for History" and under the Settings for that option I made sure that only "cookies" and "cache" were checked. After I restarted, the History tabs are still activated. I have included a .jpg file of the current mode.
