[BUG] Exclusionary rules to the Injection blacklist settings are ignored

Sequence of actions:

1. Set the following Injection blacklists under the Blacklist settings:

file://*/*
@exclude-match file://*/*.webm

2. Install the following userscript:

https://github.com/WhatIsThisImNotGoodWithComputers/webm-looper-userscript/raw/master/webm-looper.user.js

3. Open a local WebM file in the browser (e.g., file:///home/user/Downloads/sample.webm).

Problem:

Our userscript fails to execute indicating that our exclusionary rule was ignored. When clicking the greyed out Violentmonkey extension icon on the page that our WebM is playing in, the following message is displayed:

Blacklisted in Violentmonkey's settings
file://*/*

I tried these other following exclusionary rules which produced the same result:

@exclude file://*/*.webm
@exclude-match *://*/*.webm
@exclude *://*/*.webm

Expected result:

Our userscript should execute due to the inclusion of the @exclude-match rule.

Devtools console contents:

Environment:

• OS: Debian GNU/Linux 12 (bookworm) x86_64
• Browser: Mozilla Firefox 142.0 (64-bit)
• Violentmonkey Version: 2.31.0

Reproduisez la configuration de blacklist signalée avec un fichier WebM local et le userscript lié dans Firefox. Inspectez les points d’entrée de la blacklist et de la mise en correspondance des exclusions ; le travail est terminé lorsqu’une règle d’exclusion autorise le userscript sur les URL WebM correspondantes, tandis que la blacklist file:// plus large continue de bloquer les autres URL.
