This is going to be a short one, mostly so I've got a reference for the future.
It seems Chrome as of v86 (latest at time of writing - at least on Linux) is hiding the full URL unless it is selected, instead showing only the domain. This is to highlight fraudulent websites for people who can tell the difference between www.google.com and www.google.evilsite.com but get confused when there is a huge set of valid-looking path and parameters after it. It seems that's about 60% of the web using population.
Anyway, if you're in the 40% and you find seeing the whole URL quite useful thankyouverymuch and don't want to have to select the bar to see the information, then you can disable this new feature.
Put this into the task bar:
Then search for and disable:
Restart Chrome and lo, the URLs are back where they should be.
