How to make masonry grid work fine under firefox?

Question

Mozilla Firefox

Good afternoon. There is a site on wordpress where post announcements are displayed as a masonry grid:
fotoart.org.ua/ru/animals/cats
Everything works fine under chrome, but firefox does not want to correctly display the grid, unnecessary spaces and indents are formed between its blocks. As I understand it, firefox cannot correctly calculate block sizes and display correctly. How to solve this gap? float: left doesn't help with blocks.
Thanks for the help.
