Why do I have to renew my add-ons every day
I have used the refresh Firefox option, but still the same. All the add-ons open in a new page and I have to re-install each, 1 by 1. That leads me to suspect a setting somewhere. I have 2 computers, but this only happens on the 1.

There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
You can check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory:
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
It is possible that there is a problem with files in the profile folder that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
See "Corrupt extension files":

If you see disabled or not compatible extensions in ""3-bar" menu button or Tools > Add-ons > Extensions" then check if there is a compatibility update available.
- click the cogwheel button (left of Search bar)
If this didn't help then delete add-ons.json and possibly prefs.js in case there is a problem with preferences.
