Tiktok unresponsive script

[Harkonnen]

https://www.tiktok.com/

Opening any page on tiktok puts PM 28.15 into unresponsive state with 100% CPU usage until it eventually shows an "Unresponsive script" popup. Works in Chrome and FF.

[Moonchild]

There's a reason why the unresponsive script dialog shows you the name/url of the script. That's important information to mention when reporting such things.

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

not sure if this it what you need?

Same on Pale Moon 28.16

Confirming on current trunk. The most curious about this issue is just how much JS is being used in such a sloppy way on the website!

JIT hangs up just after what appears to be an unterminated string literal:

Line 6 correlates with "window._I18N_LANG_MAP_" on the index of this website (Unminified: https://pasteall.org/zgex/raw ) which is later needed by "window.registerIntlMessageFormat" in _app.js (Unminified: https://pasteall.org/yBHk/raw ). Basically it's trying to meddle with cookies and crashing in a bad way due to the missing I18N string (At least on my GNU/Linux Box). If it were coded properly it should fail gracefully rather than hanging up the browser...

[Psycho-A]

Same for me on PM 29.1.1 on Windows, but I can't even see "not responding" dialog - browser just hangs forever with 100% CPU until killing it with Task Manager.

[_yuyu_]

There was the same problem for me with Tiktok. Since PM 29.1.0 no issue anymore.

[badnick]

TikTok works fine for me at this moment but you can expect anything from day to day from Facebook related pages.
