Cross-Origin Request Blocked

more options

I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

You need to provide a error reporting for others whom can check on such errors to know what is happening. You also need to provide how to replicate the error step by step so others can see what happens if they do the same.

I attached an image of the errors I am seeing in the console in my original post. Is there some other error report I need to provide? Here are the steps to replicate:

1) Open Firefox and go to youtube.com. 2) Click on any video. The video will continually load but never play. 3) Hit F12 to open the console and see the Cross-Origin Blocked Errors.

I am using version 133.0 on Windows 11.

@markwarner22 I don't have any addons/extensions installed. As I mentioned, I've done a complete uninstall of Firefox and then reinstalled it. So its just a blank slate and I'm still having these issues.
