But… I "need" those tools to undo the harm that some websites try to inflict on me. I use them almost daily to delete things like taking 25% of my window for a scrolling and animated banner trying to sell me their irrelevant-to-me Excel add-in (annoyingly, this example bypasses all adblockers, comes with a widget that resizes it to a 'mere' 5% of my window, and forgets my choice every time I load or reload any of their pages). I also sometimes use them to repair malfunctioning pages so I can actually use them as intended.

Sure, you could say that I should just use this "Developer Edition", but that requires me to have access to install it on every puter I walk up to (just to be prepared for somewhat common web attrocities like full-page elements that prevent me from interacting with the page in ways that I feel should never be forbidden).

I don't tend to see 'warning' messages in the dev console that seem to be attempts to dissuade me from using the dev tools. Maybe…twice in >20 years?
