A Microsoft file hosting and synchronization service.
Hi,
I've just had this issue in Firefox too. What worked for me:
Firefox >
Settings (hamburger menu, top right) >
Privacy & Security (sidebar) >
Cookies & Site Data (main pane)
Click on "Manage Data"
Enter "Live.com" in "search web site" field
Make sure live.com is highlighted in list & press delete key to remove all cookies (this will log you out of OneDrive in the browser)
I closed the browser window I had been using for OneDrive (not sure if this is absolutely necessary. But [shrugs])
open a new browser window
log in to OneDrive
Resolved Error 103/flashing window & I can now view recent files
HTH
