A recent development has come to light regarding the use of ad blockers on YouTube when accessed through the Firefox browser. Users have reported a five-second delay when playing videos, which has been linked to Google’s efforts to combat these programs.
One such user, identified as vk6, shared their experience on Reddit, showing that when they played a video on YouTube in Firefox, the screen went black for several seconds before the video started. However, when they switched to Chrome, the video started playing automatically.
The cause of this delay is believed to be related to the use of ad-blocking extensions in the Firefox browser. In the uBlock Origin Reddit forum, users claim that this delay is not a Firefox bug but rather a code that Google has inserted into YouTube. This code has been identified as 5E3 in the polymer script link.
YouTube confirmed in early November that it was implementing global measures to combat ad blockers in browsers. This included an increase in warnings urging users to avoid using ad blockers or subscribe to YouTube Premium. Additionally, if users continue to use ad blockers, the platform may block playback of videos altogether.
As a result of these measures, there has been an increase in uninstalls of ad blockers and installations of alternative ad-blocking programs such as AdGuard, AdLock, and Ghostery.
Overall, it seems clear that Google and YouTube are taking steps to ensure that users are not able to bypass their advertising efforts through ad blockers. While some may see this as an infringement on user privacy and choice
