Good Tested on Firefox and Brave browsers. Using version 0.31.5 causes the YouTube Live DateTime Tooltip script to stop working. This issue does not occur with version 0.31.4.

Good This script is so good. However I have a problem when opening 2 tab of YouTube. While the first one just works fine, the second one keeps not responding or very slow.

Good Latest update crashes my YouTube. The page starts loading up normally, video plays for a few seconds and then the page becomes unresponsive. Previous versions were fine. Brave/Tampermonkey.

The update broke the homepage. The functionality on the left-hand side is gone, along with the personal center and subscriptions. It feels like I'm not logged in.

Good 不好意思，和廣告攔截腳本同時開後導致畫面黑，F5的瞬間能看到封面 https://greasyforks.org/zh-TW/scripts/480192 由於兩邊都剛更新過，無法確定哪邊衝突不好意思，先問看看。 倒退歷史版本也一樣會黑畫面 目前CHROME和CENT都會這樣
