This problem can sometimes be caused by disabling or refusing to accept cookies.

Good day, i met next issue with Coockes transfer during redirections (i suppose that). I.e. when i try to download smth from Google drive i got: An error occurred during a connection to doc-0o-ag-docs.googleusercontent.com. This problem can sometimes be caused by disabling or refusing to accept cookies. I try to follow standard advises such as disable tracking and cookies blocking (as well i disable fingerprints and all addons and delete all cookies and history storage and it's didn't help at all). I try to download in private mod as well, but got stacked with same issue. With Chromium all works fine. Firefox version (nightly): 78.0a1 (2020-05-28) (64-bit) I try to download with vanilla Firefox - same result.
