Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates. On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords. Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this. I've read through a ton of articles, and I can't seem to find a fix.
