I followed the steps in the unable to save preferences page, but I noticed EVERY time I exit and return to FF, my screen settings are NOT saved, and the pref.js file has the read only box checked even though I unlocked it when not running FF. I even deleted it at one time. I had nothing running that blocked the file. The only app that "might" do it is Kaperskis, and in that I had everything off pertaining to browser protection. I am running Windows 10 pro. Is there a windows setting that might block unlocking of the file?

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.
