[AjiTae]

Actual Behavior

Script does not run after F5 in UserScripts API Dynamic mode.

Expected Behavior

Script should run.

Steps to reproduce the issue

1. Open new tab.
2. Go to typescript playground
3. Script runs.
4. Refresh page by pressing F5.
5. Script does not run.

Environment (please complete the following information)

• Browser and Version: Firefox 145.0.2
• Tampermonkey version: beta v5.5.6232
• Operating System and Version: Windows 10

Script

Please give an example of the script or its installation URL if applicable.

// ==UserScript==
// @name         test
// @match        https://*.typescriptlang.org/*
// @match        https://typescriptlang.org/*
// ==/UserScript==
console.log('tm-script-executed')
document.documentElement.innerHTML = 'tm-script-executed';

On this site (https://webbrowsertools.com/test-webrtc-leak/), whether in chrome or in firefox, when inserting an iframe (the iframe is not empty, but there is actual content) with src pointing to about:blank asynchronously, TM does not inject script into this new iframe. Comments and feedback is the location where the iframe is inserted.

To be honest, Tampermonkey has many problems in handling iframe script insertion. (#2313, #2593)

@Maxwelline this issue is not about frames; it is about URLs with query (?xxx) parameters. I think these are separate issues.

At the moment I have no idea, why it doesn't run after F5. The userscript is registered, but Firefox simply doesn't execute it.
