Firefox doesn't caches static resource

Firefox doesn’t caches the static resource, all static resources have been reloaded.
Please check attached file.

Firefox version: 66.0.2 (64-bit)

Hi @sonle, can you clarify if this is a devtools or a Firefox issue?

When I test (66.0.3 on 64-bit Windows, new private window), I get 304 statuses for the .jpg and .png images on reload.

Could you make sure these preferences have their default values in about:config:

  • browser.cache.check_doc_frequency
  • browser.cache.disk.enable
  • browser.cache.memory.enable
