Parchment not working with Glulx files?

When I go to iplayif.com and play a local glulx file, either a .ulx or .gblorb, I get the following error:

TypeError: Content-Length header of network response exceeds response Body.

I tried a local Z-code file, and it worked fine.

Anyone else seeing this? My browser is FireFox 128.6, is that too old?

I’ve never seen that error before, and have no idea what it would even mean in the context of a local storyfile.

Firefox 128 is from last year? That’s probably not too old, I’ve barely touched Parchment at all this year.

Anyone else able to reproduce this?

I don’t repro that.

I just tested The Wizard Sniffer https://ifarchive.org/if-archive/games/competition2017/The%20Wizard%20Sniffer/The_Wizard_Sniffer.gblorb by downloading it locally, going to iplayif.com, clicking the “or click here” link on the home page, and selecting the .gblorb.

It worked in Chrome 139, Firefox 142 and the latest Firefox ESR “128.14.0esr” on my macOS Sequoia 15.6 machine with an M1 aarch64 CPU.

Very odd, all the things I try are working now.

Guess I’ll see if it happens in the future, it’s probably some glitch on my end…
