I am finding users with very old unsupported Windows versions. What versions of Windows does Discourse support (I cant find this info anywhere…)

Anything that can run: [image] About support for legacy browsers Support They aren’t. Our official browser support policy is the latest version of Firefox, Chrome, Safari and Edge.

So there’s no real list. That means I have to search what browser versions all the versions of Windows back to 7 support. I see. It would be handy if there was such a list.

There are browsers that work on Windows 7 and are supported by Discourse. [image]Dropping iOS 15 & other old browsers in July 2025 For users of Windows 7 and XP who are unable to update Chrome/Firefox, you may want to consider a third-party chromium fork such as Supermium or Thorium .

Which are not listed in the supported browsers list given here on Meta Discourse.

i’m fairly certain I remember either Firefox or the ESR release still having Windows 7 support. You should have no problem running Discourse on a Firefox ESR release.

What is important to highlight is that Discourse doesn’t support any Windows version that Microsoft themselves don’t support. With that out of the way, I have tested myself that users from Windows XP upwards can get it working with minimal effort by installing a modern browser fork: [image] Dropping iOS 15 & other old browsers in July 2025 megaphoneAnnouncements Fun exercise I just did: Windows XP IE 6 gives a TLS error [The image shows a Windows with Internet Explorer displaying an error message about a page cannot be displayed with the option to diagnose connection problems highlighted in red. (Captioned by AI)] Same Windows XP using a browser that still supports it (Supermium) [The image displays a blog post from the Discourse website on dropping iOS 15 and other older browsers in July 2025, announcing that new stable releases will be outdated … Given that Windows XP is turning 25 years old, and much older than Discourse itself, it is impressive that this is even possible.

Firefox support for Windows 7, 8 and 8.1 | Firefox Help Firefox version 115 ESR will be the last supported release for Windows 7, 8 and 8.1. Looks like Firefox 115 ESR is a good bet.

[image] Falco: Looks like Firefox 115 ESR is a good bet. Nope. We’re getting angry messages from people running Firefox 115 ESR on Windows 7 stating “I cannot access the site”. [image]Dropping iOS 15 & other old browsers in July 2025 The minimum Firefox version with support for these features is v128 (July 2024)

According to Wikipedia, extended, extended support for Windows 7 ended on October 8, 2024 So that’s an insecure option to be running these days?

[image] RGJ: stating “I cannot access the site”. Did they say what the problem was? TLS negotiation failure?

Most people running Windows 7 in 2026 are not able to get any further than “doesn’t work”, unfortunately.
