Why this bug in firefox with blurred background image and broken height and white blocks?

Question

css

Hello everyone, I have a bug in Firefox. The background is blurred, blocks are lost. The problem, in my opinion, is in flex , but I don’t know how to fix it . There are prefixes.

Answer 1

.index__wrapper-left {
    flex-basis: auto;
}

For max-width 1166px.
But maybe something else will break after that :)

Answer 2

The problem is not in layout and not in prefixes, but in scripts. If you disable javascript on the page, then everything is displayed normally
