Summary
Bookmarks are great ways to save quick routes to websites or pages that you regularly use, and want to have one place to access. When you are logged into a browser, the bookmarks that you have saved will be available from anywhere you log in from through the cloud. Each browser has their own version, which means that switching browsers will need new bookmarks. If you choose to switch browsers you would need to manually find each website and save it as a bookmark in the new one.
Body
Bookmarks are a handy way to save and quickly access websites or pages you visit often. When you're signed into a browser, your saved bookmarks sync through the cloud—so you can access them from any device where you're logged in.
Each browser (like Chrome, Firefox, or Edge) manages bookmarks differently, so if you switch browsers, your bookmarks won't automatically transfer. You would need to either manually re-save each website or use the browser’s built-in tools to move them over.
Fortunately, most major browsers offer simple import and export options for bookmark files.
