Why won't my add-on settings save?

I am running Firefox Nightly 54.0a1 (2017-01-28) (64-bit) and for some add-ons my settings won't save (for example QuickNote). But if I launch regular Firefox, and change the settings they do save and then work for Firefox Nightly too. I have tried factory resetting and reinstalling, but nothing worked.

Did you do the initial check for issues with prefs?

Did you try a new profile?

Note that you should have a separate profile for each Firefox version and never use a profile with different Firefox version. This is even more important when you use unstable Nightly and Developer Edition builds.

I created a separate profile for Nightly, but that didn't help. I checked the prefs.js file and it appears that Nightly cannot modify that file or something. When I change a setting in regular Firefox that thing immediately saves to prefs.js, but that is not the case with Nightly. I ran them both on separate profiles.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

Did you check the permissions for the file?

What happens if you delete the prefs.js file while Firefox is running?

Does a new file get created when you close Firefox?

I don't have any of that. I even have windows defender disabled. The only thing I use is malware bytes.

Everything is allowed for every user. It's not read-only either,

If I delete and exit Firefox, a new prefs.js does get created. It still won't save my setting though.

I wanna mention that this is not the case for all extensions. Only for a few. uBlock origin or uMatrix settings work. The only problem I'm having is some addon name I cannot remember right now and QuickNote.
