How to remove setting from deleted extensions?
I used to have an extension. But after removing it I still see its setting in about:config. I don't want to clutter my Firefox's profile. Look at the screenshot.
1. Is it safe to remove all these setting manually? 2. How can I confirm that all the unnecessary data is removed? (including sqlite databases, etc...) 3. Isn't it a responsibility of an extension's developer to remove all the settings when a user removes it? 4. If I install hundreds of extensions and then I remove them, will they remain in my profile after deleting?
