YouTube Thumbnails Not Updating Properly with uBO Enabled

YouTube is a popular platform for watching videos, and its thumbnails are an essential part of the user experience. The thumbnail provides users with a visual representation of the video content, allowing them to decide whether or not they want to watch it. However, recently, many users have reported that YouTube thumbnails are not updating properly when using the uBlock Origin (uBO) browser extension.

The issue was first noticed on Firefox version 78.0.2 with uBO version 1.82.2 installed, but testing has shown that the problem also occurs on Chrome version 89 with the latest uBO version available (1.27.10). The issue is not limited to a specific browser or operating system, as it has been reported by users on various platforms.

When using uBO, YouTube thumbnails appear to be stuck in a state where they do not update properly. This means that any video watched appears as if it was barely started, even if the user has actually finished watching it. The progress bars in the thumbnail are also not functioning correctly, making it difficult for users to determine how much of the video they have already watched.

It's worth noting that this issue is not specific to a particular version of uBO. The problem has been reported on various versions of the extension, including the latest beta release (1.28.5b5). This suggests that the issue may be related to a fundamental flaw in the way uBO interacts with YouTube rather than a bug specific to a particular version.

To troubleshoot this issue, users have tried removing uBO and restarting their browser, but this has not resolved the problem. Additionally, updating to the latest beta version of uBO has also had no effect on the issue.

In conclusion, the issue of YouTube thumbnails not updating properly when using uBO is a frustrating one for many users. While there are various workarounds that may help resolve the problem, such as disabling uBO or using a different browser extension, these solutions are not ideal and do not address the root cause of the issue. Therefore, it's essential for the developers of uBO to investigate this problem further and provide a solution to ensure that YouTube thumbnails function properly when using their extension.

In the meantime, users who rely on uBO may want to consider disabling the extension or switching to a different browser extension until a fix is available.
