What does it say?

The text flashed really quick, but I think it says "docs-0k-bs-docs.googleusercontent.com" I don't think that I am blocking any content, because I have already allowed all cookies (at least I think I have) and disabled enhanced tracking protection for the website. I have also deleted the cookies and try to boot into troubleshoot mode, and nothing happened while in troubleshoot mode.

I tried changing my proxy settings and it made no difference. I also checked if any of my themes or extensions were causing the problem, but when I disabled them, there was no change.

I'm having the same issue. The only way it works for me is to allow all cookies. Something has changed... Let just allow the cookies in the screenshot and see if it works.

How did you get to the window that displays the blocked cookies? I have tried almost everything but no window pops up that looks similar to that for me.

Here...

Keeping my cookie setting to custom and blocking 3rd party cookies, but allowing the cookies that were blocked still doesn't fix the issue for me. If I turn off ETP the site works with my cookie settings still in Custom and blocking 3rd party cookies. see screenshot

You get this information if you click the shield icon in the location bar.

You can also check the Web Console and possibly the Network Monitor to see whether requests are blocked.

When I turn off ETP, I still cannot download anything. When I pressed on the shield icon, the menu that came up did not look the same as yours. I was able to open a menu that let you set exceptions for deleting cookies when firefox is closed, but that made no difference.

What are your cookie settings?

So it works, now that this cookie is allowed in FF95, but not Nightly. Even in Troubleshoot mode, it's still not working. Interesting...

This?

OMG! The upload server is killing me. Can someone see how many times I try to upload and failed?

It also works for me in Win11 after allowing the cookie https://doc-0c-3g-docs.googleusercontent.com Just can't get this to work in Nightly.

Setting my cookies to Strict works, but it's not how we do things round these parts.  ;-))

What are your cookie settings?

these are my settings

when I opened google drive in web console and it had this error code "This error page has no error code in its security info aboutNetError.js:584:13"

Try Strict. It worked for me, but this is how I roll. see screenshot

Unfortunately, it didn't work for me

Did you try Standard?
