Telegraph Puzzles site

Displays a blank page. Although a Telegraph subscription is needed to access the puzzles you should see the problem without.

Thanks for the new release, a great improvement in compatibility indeed.

Can't confirm.

[Moonchild]

Can confirm. So... we should compare notes

I tried disabling IDCAC and ABL clearing the various cookies but it stays blank even if satisfying its cookie policy by hand.
Web console complains about Firebase internal errors.

I did test with a fresh profile (like I do most of the time when testing something).

This site uses the ::part() pseudo-element, which we don't support yet. Implementing this will require plumbing similar to Issue #1592 (UXP).

Code: Select all

Unknown pseudo-class or pseudo-element ‘part(’.  Ruleset ignored due to bad selector.

To make these errors show up in the browser console, make sure that the layout.css.report_errors pref is set to true.

So why does it work for gepus then? We should literally not be able to display it.

[davews]

Thanks all, and strange that it works for gepus.

The Telegraph have an old puzzles site, https://puzzles.telegraph.co.uk, which works fine, but recently they introduced their new fancy site which seems to be a backward step.

[gepus]

Weird that so far I'm the only one for whom the site displays.
The only difference for my portable Pale Moon I can think of is that it is configured for permanent private browsing mode.

[Moonchild]

Yes it works in a private browsing window just fine. Richt-click the link and "open in new private window" and tada the site loads.

[FranklinDM]

Yeah, it works in private browsing mode (my initial suspicion was incorrect, sorry). From what I can tell, this might be a potential indexed DB issue? When opening the page regularly, there's this error:

Code: Select all

TypeError: this._heartbeatsCache.heartbeats is undefined[Learn More] puzzleUser.cab7f3eb.js:406:490

There's an unminified version available, which more or less matches this line. The site works in private browsing mode because indexed DB is unavailable and the code dealing with indexed DB is skipped.

[davews]

But when in a private window if fails with same blank page when you log in.

[FranklinDM]

FWIW my best guess is it's bug #1193394 (however, the site works in the last nightly without it...), but most likely, it's some change that occurred between Firefox 59 and Firefox 60.
