Checking the add on store causes what seems to be an endless loop of the icon

For several week I have been building a new system and when I look for add ons I get no returns just the rotating icon circling endlessly. This also occasionaly happens when trying to check the backup.
Reseting or rebooting does not seem to correct the problem.
Any suggestions?

What core, supervisor and OS versions are you on?

Core-Version: 2023.6.3
Supervisor-Version: 2023.06.4
OS-Version: 10.3

Try clearing your web browser / app cache.

Are you using Firefox?

If so there should be a fix coming soon.

Yes I am using firefox. I will try another browser.

Works fine with Edge browser.

I use Firefox too and clearing my browser history worked for me.

I cleared the browser history but the problem still exists. For now I will continue to use the Edge browser.
Thanks for your help!
