What "buttons icons"? When I set the "javascript.enabled" preference in Firefox 151 to "false" and reload the page for RFC 5737, I get a "Javascript disabled? Blah blah blah blah." complaint near the top of the page. I do not get

* the useless-to-me "document history" bar graph at the top

* the automatic switch to Dark Mode(TM) that I don't care about

* functional pull down menus at the very tippy top of the page that are entirely unrelated to RFCs that I give zero shits about

The "without javascript" version of the page seems to me to be otherwise identical. Amusingly, the "Email authors", "IPR", & etc buttons switch to the pages they reference notably faster with Javascript disabled.

What broken things were you seeing that I haven't mentioned? Were you using Chrom(e|ium)? Safari?

Do it the other way around - disable javascript first, clear cache/open incognito (maybe close/open browser after that just for good measure), then go to the page.

If you load it with javascript first - buttons icons stay loaded after you disable it.

The only thing that I don't do in Firefox's "Private Browsing" mode is play a handful of stupid little in-browser games that save progress in a cookie or whatever. I even have Firefox set up to open in "Private Browsing" by default. Here's what I did just now:

1) Quit Firefox

2) Opened Firefox

3) Visited 'about:config'

4) Set 'javascript.enabled' to 'false'

5) Quit Firefox

6) Opened Firefox

7) Re-visited 'about:config' and verified that 'javascript.enabled' is still set to 'false'

8) Visited <https://datatracker.ietf.org/doc/rfc5737/>

It's still exactly like I reported it was. The "Manage browsing data" thing accessed through Firefox's regular settings dialog doesn't indicate that there is any data saved by any ietf.org subdomain, and when I watch the Network pane, a ctrl+shift+f5 reload of the RFC5737 page indicates that the page loads everything from an ietf.org subdomain... so the saved resources from one of the like eight domains in that list aren't relevant.

Fascinating.

I use NoScript, not 'javascript.enabled' setting.

I checked more closely and here is what appears to be missing:

  Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://static.ietf.org/dt/12.65.2/ietf/bootstrap-icons.5b9cac4e.woff. (Reason: CORS request did not succeed). Status code: (null).

Bootstrap icons.

  Block javascript - icons won't load.
  Allow javascript - icons load.
  Block javascript again - icons load, unless tab is closed and then opened again.

This behavior has been observed previously.

I tried to selectively block css to see how it's tied to javascript.

  Block javascript, block css from static.ietf.org - icons won't load, page layout is broken.
  Allow javascript, block css from static.ietf.org - the icons won't load, layout is fine.

Evidently, with javascript blocked, layout css loads fine, but bootstrap icons only able to load when javascript is not blocked.

'javascript.enabled' setting seem to has no effect on icons. However, unlike NoScript, it does not provide any domain separation/granularity.
