[brave] page freezes, but still works in private window

[ghost]

What happened?

age restricted videos no longer load in regular window but load in private window. this bug persists on latest brave release, brave beta and brave nightly. they all had same chromium version when i tested.

on this older version the script works as expected, i have downgraded for now https://github.com/brave/brave-browser/releases/tag/v1.65.89

tried fresh install with brave having no changes except the script. tried disabling shields, using tampermonkey instead of violentmonkey, deleting all site data before opening video, changing ip, nothing worked.

google chrome with same chromium version as brave didn't have this bug.

Confirmed. This is a bug in Brave.

Filed an issue here: brave/brave-browser#37341

Issue:

Calling the XMLHttpRequest send() method after calling open() with this specific URL /youtubei/v1/player freezes the tab.

Repro:

const xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', '/youtubei/v1/player', false);
xmlhttp.send();

Are you still able to reproduce this? After having reinstalled Brave I don't see the issue anymore.

yes, just tried fresh install of brave release on linux and windows, Version 1.64.116 Chromium: 123.0.6312.105
both the script and the snippet you provided still freeze the page
on private window everything works fine

if it started working for you on the same version maybe it has to do with this thing https://griffin.brave.com/ where they randomly enable some experimental flags for users when you relaunch/reinstall the browser

Are you willing to provide feedback on the Brave issue above? They might ask you a few things.

The griffin thing you mentioned is interesting and might be related.

As already mentioned this is a browser bug, specifically with Brave. And an issue already has been filed on their repo.
