Firefox for Android doesn't load webassembly

I'm programming a webassembly site (http://ictz.net) with .Net Core & Blazor.net.

It does load in Firefox for Windows not in Firefox for Android, on my mobile phone & tablet.

It does in other browsers for Android.

Hi

This does not sound like an issue with Firefox for Android, but more like a web development query. I would recomend asking about this issue at https://stackoverflow.com/.

You think?

Why?

more options

Blazor works in Firefox for Windows. Blazor works in other mobile browsers

Blazor doesn't work in Firefox for Android.

That's why I come here first.

"Sounds like"? Well, it sounds like a Firefox for Android problem to me. But hey, that's me. And I'm #nobody.

But then again, if no 'Firefoxer' is listening here, I wasted my time here.

Oh, and one more thing: where it works and where it doesn't work was stated in my initial post here.

I really don't like to repeat myself.

"Sounds like" ... With no further explanation whatsoever.

Yeah right!

Hi

I have seen similar issues to this in the past causing errors due to the site and not Firefox for Android. The experts at Stackoverflow should be able to help you with this.

Similar issues? Really?

Why don't I believe you ...

Okay, this is a waste of my time.

Just Remember this: "webassembly" & "firefox for android"

Hell, see if I care.

Hi

I am not sugguesting that Firefox for Android has a problem with WebAssemby, but it might be a per site issue that needs to be rectified.

I AM suggesting that it (ffa) has a problem with webassembly.

That's why I posted the issue here, and _not_ on stackoverflow.

Found _any_ similar issues already? Or does it still sounds like a website problem to you?

Do you actually have any clue why I posted it here? Any experience with webassembly?

FYI:

It's not my code.

Perhaps it's the .Net Core Blazor webassembly compiler OR Firefox for Android has a problem with (compiled) Blazor webassembly. And there isn't such a thing as Blazor webassembly, Blazor websassembly = webassembly. Compiled binary code which runs in _all_ browsers.

The site runs in Firefox for Windows. And that's the _only_ reason I first posted a message about it here. You could think the webassembly engines would be the same. At least, that's is what I'm thinking.

At last, it could even be a problem with the platform it runs on (Ubuntu) or the webserver I'm using (Kestrel), but still, it runs perfectly in Firefox for Windows. Alas, my question here.

It's great if you try to help, but if you do not understand my question it's not very helpful.

And that's why "sounds like" & "similar issues" aren't helpful at all.

Just installed Firefox Focus (Android) and guess what ..

It runs in Firefox Focus.

Sounds like a Firefox (for Android) problem to me.

Hello? Anyone?

Thank you!

I thought the devs were monitoring this forum as well, didn't yet know about 'bugzilla'.

I've uploaded another screenshot with the Focus result, see above.

I know, but this is a chromium/blink engine.

No, not really.

Thank you so much for your answer TyDraniu, and for posting it at Bugzilla. Somebody else encountered the same problem, just 4 days ago, and Firefox devs at Bugzilla are picking it up.

Thanks again.
