What is the reason for the strange behavior of the site in different browsers?

Question

Online shopping

Hello.
There is a website of a fairly well-known company and many probably know about it (this is not advertising, in general, just a question).
We are talking about the online store leroymerlin.ru.
He described in detail the problem and what happened after which it disappeared and I hope forever, because it was very baked, but
because there are a lot of links in the description and in order not to be considered as advertising, the text was placed elsewhere
roman-korolev.ru/leroymerlin.ru_problem .
Basic request https://leroymerlin.ru/catalogue/search/?q=Curtain
which usually had problems (does not depend on the request) and for which product images were not shown.
As I understand it, the problem is either with the certificate, or with the caching of the certificate, or with checking this very certificate, but these are my guesses.
What could be the real reason? Maybe someone had a similar problem?
The situation repeated literally exactly the same and there is no other site like this

Answer 1

Is the issuer of the certificate, by any chance, "Kaspersky Anti-Virus Personal Root Certificate"?
Then turn off your antivirus and refresh the page.
