Turning off Brave Shields or any other adblocker can bring it back to normal, it should be a problem caused by site scripts conflicting with TM and adblocker.

[j4k0xb]

That's unfortunate... This site is infested with ads
Gonna look what filter in https://github.com/uBlockOrigin/uAssets causes it

[derjanb]

You can also try to set Content Script API to UserScripts API Dynamic. By doing so the script might run earlier than uBO's injected filter snippets.

@j4k0xb It could be a script conflict, not related to filtering rules. And the console didn't get any useful information.

@derjanb The UserScripts API Dynamic mode doesn't help.

BTW. TM 5.3.6209 BETA does not resolve issue #2164, Whenever the browser is updated, GM_info.userAgentData returns still the original version number in UserScripts API Dynamic mode.

The same script works in Violentmonkey btw, so I think it's a Tampermonkey issue

Violentmonkey also has problems. You can try running the following script. The window.atob method will report an error. @j4k0xb @tophf

Script

// ==UserScript==
// @name        New script
// @namespace   Violentmonkey Scripts
// @match       https://streamtape.com/*
// @grant       unsafeWindow
// @version     1.0
// @author      -
// @description test
// @run-at      document-start
// ==/UserScript==

console.group("unsafeWindow")
console.log(unsafeWindow.atob);
console.log(unsafeWindow.atob("QQ=="))
console.groupEnd("unsafeWindow")

console.group("window")
console.log(window.atob);
console.log(window.atob("QQ=="))
console.groupEnd("window")

The window.atob method will report an error.

nope it works fine

with uBlock Origin?

voilentmonkey with uBO:

[tophf]

1. The order in which extensions run at document_start probably depends on which extension was installed first. If uBO runs first it mangles atob somehow. I'd say it's a bug in uBO filters, because breaking such basic functions is overly destructive.
2. Since Violentmonkey is still MV2, a real document_start requires you to enable "Synchronous page mode" option.

Hi @tophf , I already enabled "Synchronous page mode" option, but it did not work.

And I fixed it by GM_addElement to get window.atob, and thanks for your reply.
