Hi, I'm having a lot of issues trying to run games on Firefox in-browser. It doesn't matter what engine the game was made in (Renpy, Twine, Unity), there is severe amounts of lag that loads text and assets and animations in a slow, choppy way. and other errors (screens not loading even if audio does; screens being zoomed in 100-500x even for games that don't have a zoom-in option.)

When I download the games, they work fine booted from my computer directly. Things also work fine so far on Safari. It's just Firefox, and this is only an issue for me since this week, but Firefox has not updated, the issue persists even with all extensions/adblocks/VPNs turned off, and there are no changes in my computer at all. All other programs and websites, including in-browser games on other websites, work fine.

Is there something I am missing? Thank you for any assistance.

Example of diverse games I am having these errors with:

https://arbitrrrary.itch.io/with-mirth-in-funeral

https://p6ik.itch.io/hamiduki

https://deadpixeltales.itch.io/stick-to-the-plan

That has nothing to do with hardware accelleration. I can not tell what the problem is exactly, but it has to do with loading files.

So some cookie stuff, redirects, http instead of https and other obscure things that should throw a error message to the user, but don't.

For the first game, try loading it in Firefox. The unity will not load, the loading bar will not move. Then open the console on FF and look for errors. There is one where some error message about    "no-referrer-when-downgrade". If you click the hwcdn link directly, the game runs.

Maybe the file hoster or itch  changed some configuration, if games did run previously. Sounds like a combination error.

I did not try the other games, if they have the same problem.
