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

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
