Edit, they have to add a missing meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

We appreciate your report but I was not able to reproduce this issue. Can you still reproduce this issue?

Tested on:
• Browser / Version: Firefox Focus 142
• Operating System: OnePlus 6 A6000 (Android 11) - 1080 x 2280 pixels, 19:9 ratio (~402 ppi pixel density) / Google Pixel 5 (Android 14) - 1080 x 2340 pixels, 19.5:9 ratio (~432 ppi density)

Suggestions:
• Clear cache/data/cookies, disable Ad-blocker or any other add-ons (if available), or create a new profile (without syncing/importing data) and check again
• If there are any changes made to the default settings of the browser (e.g. in about:config), please revert to the default settings

@sv-calin actually you reproduced it. As you can see the content did not adapt to your screen, it is really hard to read compared with what you have on chrome (or on your desktop browser if you reduce the window width):

But I believe the issue comes from a missing meta header, so I suggested a change to the site directly with ziglang/www.ziglang.org#528

Ohh, I see. I misunderstood, based on your initial screenshot I thought you meant that the content goes off screen.

I've created a new report on bugzilla for this issue, for more info check: https://bugzilla.mozilla.org/show_bug.cgi?id=1986273
