On Chrome based browsers you can view and change browser settings on a per site basis. To the left of the the URL field there is a padlock (for sites that use https). Clicking on this will bring up a pop up box, with certificate, cookies and settings. In this case certificate valid, cookies 9, settings. If you click on Site settings, this will bring up a new page, where you can view and change settings.
What you need to change will depend on what defaults your browser has implemented and what plug ins you have. These can be disabled per site. Extensions, manage extensions. Various versions will have a different layout but hopefully this gives some idea.
Cookie persistence may be an issue, hence the question from
@Good CO about Incognito mode.
