Why try it on another browser?
To see if it makes a difference. If not, there is little point in trying different browser settings.
Try the easy things first, rule out some common issues, then try the harder things.
If manually erasing cookies helped last time, try a private or incognito browser window.
Try changes that can be easily reversed before you start making changes that cannot be undone, like deleting things or messing with your settings. That way you do not inadvertently make things worse.
