If you use both from the same IP without using a VPN… the profiles are most certainly grouped. There are commercial datasets on IP addresses with almost 100% accuracy with tags like “school”, “house”, “apartment block” etc. Furthermore, if you ever logged into both sites from within the same browser by accident, the link by fingerprinting was made right there and then. The final profile on you may not be 100% accurate, but certainly is in the 98% range.

It's one thing if they have a shadow profile on you (and dozens of companies almost certainly do), but it's another thing if you give them meaningful info about you to enrich that profile with. They can figure out roughly what block you live on, OK fine, but unless you're in a rural area with no neighbors they might not be able to do much better than that.

> They can figure out roughly what block you live on

Its nothing to do with the specific house you live in, and everything to do with the activity being grouped together with all other activity you have done, which they know from fingerprinting and IP addresses.

They dont need to know where you live to have a very accurate personal and psychological profile opn you, and switching browsers is not going to help that in the slightest Im afraid.

		Yes and no. If you block Linkedin SDK scripts on 3rd party sites, it's likely that Linkedin specifically doesn't actually have a good profile on you. Realistically you're probably exposed and identified. But if you're meticulous and careful, you might not be, or at least not as completely as someone who is unaware or not careful. But it's not at all the same as if, say, a state actor was motivated to spy on you specifically.
