leroymerlin.ru - most pages misrendered

Unread post by motoprogger » 2022-08-13, 10:58

leroymerlin.ru is the website of a construction material shop. Most of its pages are rendered the wrong way, but the main page has suffered the most.
This is the main page: https://leroymerlin.ru/
This is an example page of the goods sold: https://leroymerlin.ru/product/truba-po ... -18746724/
The errors visible in the console when rendering the main page are:

Code: Select all

StrictTransportSecurity seems to complain for every resource fetched from this domain. This is the example header of the main page itself:

Code: Select all

Strict-Transport-Security: max-age=31536000; includeSubdomains; preload, max-age=31536000; preload
The only network error is 404 on https://get.shoppilot.ru/f/v1//__omnibo ... mnibox.css

The errors thrown are pretty self-explanatory. Pale Moon is blocking a stylesheet (which is likely why it renders poorly) because they specify "nosniff" but the css file in question doesn't match the sent mime type. So either it's not a css file or they send the wrong mime type header. That is a server-side issue
So is throwing invalid STS headers at the browser.
The webmaster needs to fix their server config. Either lay off the STS and nosniff, or make sure what is sent is to-spec.

The resource in question of

Code: Select all

The resource from “https://get.shoppilot.ru/f/v1//__omnibox_v2__/styles/omnibox.css” was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).  leroymerlin.ru
Is the same as the resource mentioned later as giving error 404. This URL produces an actual error 404 if I try it with wget.
Firefox 91.11.0esr (64-bit) renders this page OK despite complaining:

Code: Select all

GET https://get.shoppilot.ru/f/v1//__omnibox_v2__/styles/omnibox.css	[HTTP/2 404 Not Found 37ms]
The resource from “https://get.shoppilot.ru/f/v1//__omnibox_v2__/styles/omnibox.css” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).	leroymerlin.ru
So I suggest that CSS missing doesn't contribute to misrendering this site at all. Probably the reference was left carelessly when upgrading the website.

Unfortunately I can't investigate because I get this:

The website somehow prevents me from downloading the page with wget (401 Unauthorized even with User-Agent set the same as Firefox), but allows to see in a browser. Here is what I've downloaded with Firefox. It still makes some network activity on open, but the top part keeps rendering correctly in Firefox and not in Pale Moon with network disconnected.

This website requires ShadowDOM and customElements. ShadowDOM polyfill rejects to work in Palemoon with error: ':not(:defined)' is not a valid selector
