Seems like a great plugin. Unless I am misunderstanding the plugin’s purpose, the example topics you’ve supplied don’t seem to be displaying the links as timestamps though.
I used Firefox to test this out. I can confirm that viewing in chrome does work though.
Looking in dev tools for FireFox this is whats rendered in html for each timestamp:
<li>
<p>0:00 - what are the constants of experience?</p>
</li>
In chrome, this is whats rendered:
<li>
<p><a href="https://www.youtube.com/watch?v=yXZSeiAl4PI&t=0s" title="View the video yXZSeiAl4PI at 00s">00s</a> — recap of jung, archetypes</p>
</li>
So checked the console in Firefox and got SyntaxError: invalid regexp group errors.
Turns out Firefox doesn’t supported named capture groups for regular expressions:
Going to mark Firefox as unsupported, however seems they are working on it - perhaps will land by the end of the year looking at current progress on their side.
Will update the readmes accordingly, thanks for the heads up!
