Environment:
Operating system: Windows 10 Pro
Firefox version: :Firefox Nightly 86.0a1 (2021-01-15)

Preconditions:
ETP Strict enabled

Steps to reproduce:

  1. Navigate to https://wasmweekly.news/subscribe/
  2. Type in the email address.
  3. Click the “Subscribe” button and observe behavior.

Expected results:
Email subscription is performed and a notification message is displayed.

Actual results:
Email subscription is not performed and no result is returned.

Notes:
Not reproducible with ETP set to STANDARD.

We've blocked beautify.us7.list-manage.com in TP which causes this breakage. Actually, the email has been subscribed but it just won't show the result because the script is blocked.

Severity: -- → S3

The issue is still reproducible.

Tested with:

Browser / Version:Firefox Nightly 87.0a1 (2021-02-18) (64-bit)
Operating System: Windows 10 PRO x64

We could possibly create a shim which listens for requests to https://beautify.us7.list-manage.com/subscribe/post-json and unblocks it, if the user is in the middle of submitting a form. The trick will be to detect whether the request is caused by a user-initiated form submission.

Blocks: tp-yellowlist
No longer blocks: tp-breakage
