Obviously, he is now developing his own block explorer, where he added new features (like identifying P2SH addresses) recently.

Can't wait to try it

Many thanks for these updates, SFR10 and 1miau!
You're very welcome

I think there's a problem with my Firefox. I did clear the cache, but still the problem persisted. However, the site loads well when I open Firefox using Private mode or when i use Opera, Microsoft Edge and Chrome browsers.
Maybe there's some extension on my Firefox browser messing things up, though I am not sure which one.
I had a similar experience with Chrome, so I used the incognito mode to record that video and that's why I thought it might have something to do with the cache, but upon doing more research, some users were also claiming an extension might be the culprit... Having said that, disabling and removing all of my active extensions didn't improve the situation in question.
- I noticed when I was getting the /undefined issue, the Timechain's version was different from the live version [currently is at v0.2.20] and from what I understood [credit goes to "this user"], the manner in which you clear the cache matters as well, so please also try doing the manual route on Firefox and see if it works:
- Settings > Manage more settings > Privacy & security > Cookies and site data > Manage data > Search for its name > Click its name > Remove selected > Save changes > Remove.
