How to clear browser cache on windows 11?

Really need help on this. My browser is acting a bit sluggish on Windows 11 and I'm pretty sure it's time for a cache purge. I also noticed some websites aren't loading correctly, and I've heard that clearing the cache can help, but I want to make sure I'm doing it the right way without accidentally deleting my saved passwords or important settings. I'm not tech-savvy and I'm unsure of the correct steps. Could someone please explain the simplest method to delete or clear browser cache for Chrome, Edge, or Firefox on Windows 11? I want to make sure I'm doing it properly without deleting important data.  Thanks
