Good advice. What I usually do is also create a few chrome profiles. One for Discord, one for Gmail, one for Shopping, etc.

Firefox is also great for this kind of thing with custom container tabs.

I use full on custom profiles for stuff like banking, shopping, etc... and containers within the profiles to separate amazon from walmart, etc.

edit: I probably should have mentioned, this is on Firefox

If you want a more robust isolation, consider using Qubes OS with hardware-virtualized VMs.
