Affected versions

• latest Nightly 126.0a1

Tested platforms

• Affected platforms: Win 11, macOS 13 and Ubuntu 22.04

Preconditions

• Standard setttings is applied in about:preferences#security
• Set “privacy.query_stripping.enabled” to false in about:config.

Steps to reproduce

1. Navigate to https://en.wikipedia.org/w/index.php?title=Main_Page&wprov=
2. Right click on the link, then click on "Copy Without Site Tracking"
3. Open another tab and paste the copied linked into the URL bar.

Expected result

• The query parameter wprov is correctly stripped from the URL, as per https://phabricator.services.mozilla.com/D203080

Actual result

• The query parameter is not stripped from the URL.

Regression range

• This is not a regression. It can also be reproduced with Nightly builds after the extened list of parameters was added.

Additional notes

• There's a possibility that the Wikipedia link tested with the specific parameter "wprov" may not have been properly constructed. In such a scenario, this outcome might be expected.
