Why does my online store backend keep constantly reloading?

[bnstore]

Hey,

I've been having an issue with my backend for the last month or so since the Shopify updates where they will just continually reload, making it near impossible to make any store adjustments or product updating without finding some silly way, which even then I can't save product info updates as it will take me back to the sign-in and fail to update.
Only on my computer, my phone app has been fine and my webpage for my store works fine and orders work perfectly fine. It's just my backend constantly reloading to the sign-in page every time it refreshes or I change backend areas (going from Products to Analytics, to Live view to Settings)

 I use firefox if that helps.

Please help,
At a loss store

Having the same problem and also using firefox

I had to download the chrome extension to get it to fix the reloading/error issues I was having as cache/cookie and incognito didn't work for me as solutions. 
It's working fine on chrome.
