Does all Mozilla (versions above 51) load pages slowly?

Question

Mozilla Firefox

I noticed that Mozilla barely loads pages, this is especially noticeable in Avito. even uploading photos is very late. Judging by the console, there is a delay in server responses, but it's worth putting chrome - everything flies. With Mozilla version 51 - everything is more or less tolerable.
Tell me, please, how to be? With pleasure I would climb onto chrome, but my eyes get tired of its muddy fonts.

Answer 1

Firefox 54 - everything works great.
