I am about the furthest thing from a computer/IT expert, so I will leave it here for others more savvy than I to chime in with tech tips and advice for you. However, if you haven't already done so, click on the vertical row of three dots in the upper right corner of your Chrome browser window and that will open up your browser settings. There you can select your desired levels of security, privacy, etc. There's a "Settings" selection at the bottom of the pop-up menu that takes you to most of your selectable items. (Sorry if I'm telling you something you already know.)
I should have also mentioned that your hardware and operating system can greatly affect web browsing speeds and response times. My wife's Apple Macbook Pro browses the web WAY faster, with fewer ads, than my Dell laptop....on which I've tried several web browsers (Chrome, Edge, Firefox, etc.) Mozilla Firefox seems to give me the best overall performance for web browsing.
