I don’t think an average person would listen to me if I instructed them to get rid of chrome and get Firefox and install couple extensions for privacy.

So, I just ask them to download brave and tell them it’s just chrome but better,  It blocks all the annoying stuff on the internet and atleast they will stop using the hell of a pacifier that chrome is and move on. 

Ublock Origin is the only mandatory extension i can think of.

Some other extensions I personally use are:

Gesturefy is useful if you want to control things with mouse gestures (holding right-click and then drawing a shape to activate commands)

NoScript for a little added security, with the cost of having to manually enable javascript on websites that literally can’t function without it.

Any extension that runs userscripts.

Dark Reader for websites that don’t offer a dark mode.
