There are a few Chrome extensions that help delay or control the loading of YouTube content. One highlight is 'Untrap for YouTube', which allows users to selectively block YouTube UI elements and focus only on content from subscribed channels, thus circumventing algorithmically-generated suggestions. The free version offers basic functionality, while the pro version promises additional features such as delayed launching of YouTube. Another tool mentioned is 'LeechBlock', which has been utilized on Firefox for similar purposes. User comments also noted the challenges posed by the transition from Manifest V2 to Manifest V3, which affects the configuration capabilities of these extensions. This highlights a broader challenge in maintaining customizable browser experiences as web technologies evolve.
