I have updated the site. New features:
- Safari and Firefox on windows should now work.
(you may need to clear the browser cache)
- Code templates ('snippets') - has Ctrl-J shortcut (as in Lazarus, I believe)
- You can now configure your own examples and snippets.
- Help page at https://live.freepascal.org/help.html
- Embedding guide at https://live.freepascal.org/embed-guide.html
Both help pages are reachable from the main page.
I put the sources for the site online:
https://gitlab.com/freepascal.org/fpc/live-pascal
It uses a Creative Commons CC0 license, for those that are into licenses.
(Gitlab forces you to put a license, and CC0 comes closest..)
I'll update with new some new features one by one.
Suggestions always welcome.

The default browser on this machine is MS Edge and potential GPO enforced security settings are more likely to be in place for that one - but it works there (as I realized now). If I open the page in an anonymous window of Firefox, it also shows the out of memory error in the browser console, but it breaks even before getting to the point of enabling the buttons, i.e. I see "Loading compiler..." and the buttons are disabled. I guess that there should be some mechanism for the page to demand more memory from the browser and it probably asks for less than what is necessary on both Firefox and Safari (whereas it works in Chrome derived browsers apparently). Interestingly, it works from Firefox running on a mobile phone (Android). So yes, it's likely related to the browser, but that doesn't necessarily mean that I could or should fix it on my side... No, but without knowing the cause there is little I can do... I use firefox only, and it has worked all through the development cycle. I also use uBlock origin. I was on a linux, though I don't see how that would matter. The good news is: I can reproduce the issue in Safari: it fails with a 'out of memory' So I'll do some testing on safari. First web search is not making me optimistic, seems safari and wasm are not a happy couple.

This function seems to be in StrUtils, not SysUtils, but that unit is not in the library. I couldn't get it to work either.
