Somehow firefox updated even though I have it set not to do that on its own. Now my theme won't work and any customizations I make (moving buttons and making tabs not on top) will not stick. It does until I restart the browser and then it's back to the original. Even more annoying, I set it to only notify me of updates and every time I restart it, it goes back to automatic updates. It undoes every single change I make. How do I fix this?
