* AmazonKids-FreeTimeApp-fireos_v3.67_Build-76.0 Here's the changelog of updated system components and their versions. So I decided to update my Fire HD 8 (2020) running 7.3.1.9 to 7.3.2.4, and with this update the system webview was updated from version 87 to version 94, and then subsequently to version 104 via the OTA, as well as the Android security patch level increased from to. I tried finding an update to the system webview but I wasn't able to find one, even after coming upon 's collection of updated Amazon apps (which inspired this).
One of these updates is for the Amazon System Webview. Unfortunately, disabling OTA Updates via the FireToolbox (thanks or creating some DNS blackhole effectively stops these from updating. These system component updates are installed by DeviceSoftwareOTA via Settings > Device Options > System Updates, and not via the Amazon Appstore like how it is with Google Play Store on non-Fire tablets. You can skip to the downloads below if you don't wish to read more. Here you can download updated system APKs pulled from Fire OS 7.3.2.7.
