Seller Hub Issue: Menu items are missing using Firefox Browser...

[agw00461699]

Under the "Seller Hub" title all of the menu items are missing such as Overview, Orders, Listings, Marketing, Advertising, Store, Performance, etc. This issue is not seen on the Chrome browser.
See the attached screen shot for details.

Try holding down the shift key and refreshing the page. If the issue involves cached content, that may help.

If not, try temporarily disabling add-ons such as ad blockers to see if that affects the issue.

I'm using the same version of Firefox and not having that problem. @eburtonlab 's advice is the best first step. You could also reboot your computer if you haven't already done that.
