Firefox Community Forum

Every time I change the settings in the image attached, once I close the browser, the settings are reversed back. My changes do not persist if Firefox closes or my PC turns off. My other settings persist when I make changes. I only get this error when I try to edit the Privacy settings.

What is causing this, and how can I stop it?

Windows 11 Home Firefox up to date with 140.0.4 (64-bit)

I would like to inspect the data that would be removed if I checked the "Settings for Clearing History > Data: Site settings"

From earlier experimentation, I observed that checking that box removes some persistence data that the ChatGPT web site uses, for instance. I also observed that it removes "Exceptions - Cookies and Site Data" that I have entered (not sure why, because it's data I typed, not data that the web sites are saving on my machine).

But the question is what steps are performed on what tables in the current user's profile folder. If not all contents are removed from a folder, please specify what the deletion criteria are.
