Details

User Agent: Mozilla/5.0 (Android 14; Mobile; rv:138.0) Gecko/138.0 Firefox/138.0

Steps to reproduce:

  1. Open Firefox for Android.
  2. Visit a new (uncached) website — e.g., example.com.
  3. Note the time it takes to load (~5-10 seconds).
  4. Now clear the browser cache via Settings.
  5. Reload the same site — it loads much faster.
  6. Try another uncached site — same delay observed.

Actual results:

Significant delay (5-10 seconds) on uncached websites until cache is cleared.

Expected results:

Uncached websites should load in a reasonable time without requiring cache to be cleared.
