--------------------------+-----------------------------
 WordPress 6.9.4.
 Element "**Galerie**" (in addition "Simple Lightbox" 2.9.5).
 More than one row of pictures on a page.
 Galerie-configuration:
  - NO crop of the pictures.
  - Aspect-Ratio original.

 The first row of pictures in the first galerie on the page is Okay. Each
 picture has its individual aspect-ratio.
 In the following rows the **pictures have a unique size**. They are
 **streched** to 2:1 to fit this size.

 This happens only with the latest Firefox-Browser 150.0.1 on Linux or
 Windows.
 The error NOT occurs in Brave, Edge or Chrome.

 The following change fixed the error for me:

 File "/wp/wp-includes/blocks/gallery/style.css"

 OLD
 {{{
 .wp-block-gallery.has-nested-images figure.wp-block-image img {
   display: block;
   height: auto;
   max-width: 100% !important;
   width: auto;
 }
 }}}

 NEW
 {{{
 .wp-block-gallery.has-nested-images figure.wp-block-image img {
   display: block;
   width: 100%;
   height: auto;
   object-fit: cover;
 }
 }}}

 Minimize to /wp/wp-includes/blocks/gallery/style.min.css

 Some say the css is wrong, others say it's a bug in Firefox.
