Add-ons file location
Hi,
Where does Mozilla Firefox saves the files from add-ons? Don't know if it is from Windows update or from Firefox update, but my add-ons settings keeps on resetting and I lose a lot of data from them because of that. And if I know where Firefox saves those files, then I can make a backup for them.

Most add-on data is stored in a folder in the Firefox user profile. However, some information is stored in the profile folder also. It’s possible that there is a problem with the file(s) that store the extensions registry. Type about:support in the address bar and press enter. Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox. Delete all extensions files and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required. After, restart Firefox. See "Corrupt extension files": +++++++++++++++++++++++++++ You will have to approve the updating one last time.
I think it was from Windows update. But your answer helped me to find the location where the extensions save their files, and I found the file I was looking for.

Separate Security Issue: Update your Flash Player Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).
Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

These can't get your data back, but will help in the future.
These add-ons can be a great help by backing up and restoring Firefox
https://addons.mozilla.org/en-US/firefox/addon/febe/ FEBE (Firefox Environment Backup Extension)
FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backups of files that you choose.

What is the point for this post? It is way out of my question.

OPIE would have been good, but unfortunately it doesn't see the extension that I wanted to backup.
