PM 30.3.0(.1) white page on https://www.duolingo.com/

On PM 30.3.0/30.3.0.1 (Linux, GTK2, 64bit) the site https://www.duolingo.com/ opens as a white page. The contents of the page isn't loaded. I tried to clear cache and restart Pale Moon. Nothing helps.

The page seems to load OK for me on Windows 10. (I don't know anything about that site.)

Confirmed blank white page for me. Windows 7 64-bit and PM 31.3.0.1 64-bit here.

Console output:

Edit: Whoops, I forgot to let everything through eMatrix. After doing so I still get a blank white page but a much more informative and reasonable console error:

Why are you using an unsupported version of Pale Moon instead of the latest? The 30.x line was retired due to severe bugs and the current version is 31.3.0.1, which reverts support for Firefox extension installation, so in case that was a concern you can continue clinging to decades old extensions without worrying about them getting disabled.

I think he's actually using 31.x and made a typo. The 30 series never got as far as 30.3.

I'm still on 31.2.0.1 and the page opens and stays white for me.

Blank page for me too. Pale Moon 31.3.0.1/Win7.
The site renders in Waterfox Classic (Firefox 56).

The problem is highlighted in BenFenner's second picture:

Since the OP is using linux Pale Moon and I use linux Pale Moon, after clicking on the OP's link which he/she provided, the page opens to a completely white page for me as well.

Vanilla is probably correct with his assessment.

Sorry, it is indeed 31.3.0.1. That's my inattentiveness.

The problem is from:

Code: Select all

I = e => e.normalize("NFD").replace(/\p{Diacritic}/gu, "")
This is a feature called Unicode property escapes, not a very new feature indeed — Firefox 78 supported it. The problem would be solved if Pale Moon updates(?) its regex engine.

It's a complex piece to implement, which is why it's taking a long time. Stuck with using a different browser in the meantime for sites that display these errors.
