Steps to reproduce:

  1. Load webpage (https://www.weather.gov/)
  2. Open Dev Tools -> Network -> toggle off then on (check) "Disable Cache" -> F5 (refresh) -- this works just fine
  3. Enter "Responsive Design Mode"
  4. Inspect any element (right-click -> "Inspect Element"; this causes the Dev Tools "tab" to change to "Inspector")
  5. F5 (Refresh) -- this works just fine
  6. Exit "Responsive Design Mode"
  7. F5 (Refresh)
  8. Select "Network" "tab" within DevTools, notice the "Disable Cache" is still checked, however, CSS (and other assets) are status 304

Actual results:

"Responsive Design Mode" does not respect "Disable Cache" whithin DevTools, leading to incorrect (cached) CSS files (etc) being loaded. Many assets are loaded with a status of 304, instead a status of 200.

Expected results:

Cache should be disabled and all assets should loaded new and not from cache; status should be 200 instead of status 304.

Status: UNCONFIRMED → NEW
Ever confirmed: true
Severity: -- → S3
Priority: -- → P3

A real "headache" but. Between this and #1661501 Firefox is getting unusable as a Development browser.
