As I mentioned in this question, I noticed Dashlane's Google Chrome extension modifying the styles on my web app when using their auto-fill functionality.
Setting the CSS properties of interest as !important prevented the injected styles from being effectively displayed. But I was wandering if there is a way to prevent these extensions from injecting styles on existing elements on the page in the first place.
I think is important to point out the word 'existing' because some of these extensions might have to add and manipulate their own elements in order to work properly. But I don't want them interfering with anything that I've created.
