After recent Firefox update, GoogleDrive is sometimes slow to load and the "Details" window for folders will not open.

Since an early September Firefox update (automatic--on my MacBook Pro running Sequoia 15.79--the subfolders of one GoogleDrive folder all became "restricted". If I try to fix them, using the settings to bring up a "Details" window for each folder, the window will not open. This happens on my home wireless and also on my University wireless connection. At the same time, same wireless, Chrome has no problem opening the "Detail" window. Also, initially, the GoogleDrive itself would not open in Firefox. This seemed to correct itself about 10 days ago (Sept 10-ish).
