Environment:
Browser / Version: Firefox Nightly 91.0a1 (2021-06-07)
Operating System: Windows 10 Pro

Prerequisites:
ETP - Standard enabled.

Steps to reproduce:

1. Navigate to https://diaonline.supermercadosdia.com.ar/lomitos-de-atun-en-aceite-dia-170-gr-55813/p
2. Perform a search (e.g "sal").
3. Observe behavior.

Expected Behavior:
Search results are displayed.

Actual Behavior:
A blank page is displayed.

Notes:

1. The issue is also reproducible for https://diaonline.supermercadosdia.com.ar/folletos, where the map with available stores is not displayed.
2. Screenshots attached.
3. The issue is not reproducible with ETP disabled.

It works fine for me which means either that this is unrelated to ETP or that there's a race here. Can you try disabling fingerprinting protection in "Custom" privacy preferences and reproducing it again?

The issue still occurs with ETP - Custom ("Fingerprinting" option disabled).

Oana, can you still reproduce?

Johann I can still reproduce it with ETP Strict now (I've updated the title accordingly).

I've created a clean profile, enabled ETP - Strict and perform a search (using "Enter" keyboard key). It seems "Search" suggestions are not displayed either, and clicking "Search" icon from the "Search" field does nothing.

Also in regards to the map, it still not displayed.
