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.
