As it turns out, there are several different potential culprits that might end up causing the Error Code F7053 1803 with Netflix:
Method 1: Turn off Private Browsing
If you’re encountering the F7053 1803 error code while streaming content from a private window in Firefox, you’re not the only one. There are a lot of users that are reporting this exact issue and Netflix even mentions it on their support page. As it turns out, the problem occurs due to the fact that Firefox restricts certain data from being exchanged while in Private Mode. Since Firefox’s Mode is even more strict than Incognito (Google’s equivalent), Netflix will refuse to stream from it. The fix in this case (on both Windows and Mac) is to simply turn off private browsing and stream content from Netflix from a normal window. You can recognize if you are currently using a Private window via its purple icon. If you see it, simply close the window, then open a normal Firefox window and repeat the streaming attempt. Note: You can do this on both Windows and macOS. If you’re still encountering the same the F7053 1803 error even after you pen a normal Firefox window, move down to the next method below.

Several affected users that were previously dealing with the F7053 1803 error have confirmed that updating Firefox to the latest version has successfully allowed them to get rid of the error.

Method 3: Enabling Cookies in Firefox

As it turns out, another fairly common instance that might end up causing the F7053 1803 error is a scenario in which your browser is configured to ‘forget’ history and cookies. In this case, you should be able to fix the problem by accessing the Privacy & Security menu of Firefox and enabling Remember history. Here’s a quick guide on how to ensure that cookies are enabled on your Firefox browser: Note: The steps below are performed on a Windows computer, but the menus for the Mac version are identical.

Fortunately, there is a focused approach that allows you to clear solely the Netflix cookie (without affecting any other saved cookie). Several affected users have confirmed that they managed to fix the issue by clearing the Netflix cookie and then signing in with their account once again.

Method 6: Using the Netflix UWP App (Windows 10 only)
If none of the potential fixes above have worked for you, one workaround that has helped a lot of Windows 10 users is to use the UWP app (Universal Windows Platform) to stream Netflix content instead of relying on your browser. This procedure will end up circumventing any browser-related issues since the streaming is done entirely through the Netflix UWP app. If this scenario is applicable and you’re willing to migrate towards the Netflix app, follow the instructions below:
