# ATTENTION

> [!NOTE]
> YouTube changes their detection scripts regularly. That means that sometime you can face the detection message.
> If all the following instructions do not work, please **email filters@adguard.com** or wait until any update is available.

> [!CAUTION]
> Please do not use another adblocker in the same time because using another adblocker can delay/lags the YouTube loading (e.g., AdBlock Plus and AdBlock)[^1] OR interfere AdGuard's filtering functionality.

> [!CAUTION]
> Please do not use an userscript related to the bypassing YouTube detection message like [TheRealJoelmatic/RemoveAdblockThing](https://github.com/TheRealJoelmatic/RemoveAdblockThing).
> Recently, YouTube anti-adblock script added infinite dummy advertisements to try to neutralize the userscript. ( [TheRealJoelmatic/RemoveAdblockThing#264](https://github.com/TheRealJoelmatic/RemoveAdblockThing/issues/264) )

> [!WARNING]
> Please check that there no another web browser extension that has adblocking feature is enabled on your web browser. It can interfere AdGuard's filtering functionality.

> [!IMPORTANT]
> Saving memory feature of your web browser or sleep feature of your operating system can interfere AdGuard's filtering functionality.
