youtube Mini Player and Fit to Window not working.

Bug Report:

The custom miniplayer is no longer working for some reason I can get it to work by toggling the setting for it but as soon as I refresh it stops working.

The Fit to Window button no longer shows up at all thus I can't even activate it. I assume it is working otherwise.

Steps to reproduce this: (Might only happen with a certain feature of our's enabled?) I installed the extension fresh on brave browser to see if I could reproduce on brave and with default settings and it looks like the fit to window button it back but the miniplayer issue did not change. So it should just be activate the miniplayer and see if it works and it shouldn't.

as for Fit to window it seems like it is a purely firefox issue I tried it on firefox base and mercury, not sure about other forks though. I imagine it is just install it on firefox activate the setting and see if it works.

Since when?: When YouTube changed something? Through our update? today 8/14/24, it was working fine yesterday.
Browser:
firefox but tested on brave as said above.
Are any errors shown in the Browser-Console?: (F12-key, then console-tab) yes so many here is a snippet: Uncaught ReferenceError: trustedTypes is not defined playerFitToWinButton

clicking on the link for the error on the fit to window button brings me to this code snippet: line 804 in player.js

ImprovedTube.playerFitToWinButton = function () {
	if (this.storage.player_fit_to_win_button === true && (/watch\?/.test(location.href))) {
		let tempContainer = document.createElement("div");
		
		// Create a Trusted Type policy
		const policy = trustedTypes.createPolicy('default', {    // <- error on this line here on trusted types not defined
			createHTML: (string) => string,
		});

also brings me to line 285 in functions.js as well as line 140 in init.js

doesn't seem to be any errors pertaining to the miniplayer though.

Does the bug not happen when you log out of YouTube? Then please copy your experiment flags list twice (with & without the error to compare). Enter: yt.config_.EXPERIMENT_FLAGS into the Browser console on youtube (F12-Key - Or find it in the html source(ctrl+U)

doesn't matter if I am logged in or not.

I feel like the Fit to window bug should be relatively easy but I am sorry I couldn't be more help on the miniplayer.

OPTIONAL (usually): -->

ImprovedTube Version (Written in the Extension header & your Browser's store) couldn't find version but the last update was appearently Aug 9 2024 for me which makes me wonder how Fit to window was working for me at all for the last few days if the error was a not defined error.
Tested as only active extension or in incognito mode?: yes the bug still appears.
Your Settings (From the Extension's ⋮-Hamburger menu > Settings > Backup & reset > Export settings (You can remove any Blocklist, History Analyzer data - or paste the following in the Browser-Console and hit enter: (function({analyzer, blocklist, ...a}){return JSON.stringify(a)})(ImprovedTube.storage) ) Uncaught ReferenceError: ImprovedTube is not defined debugger eval code:1 got this error for this command. not familiar with java script or browser consoles so I have no idea how to fix that. but I installed it fresh and all my data looked like it was purged so just the -Fit to Window and -Custom miniplayer should be the only ones besides default.

an added note: the miniplayer setting persists until you do a full refresh so I am assuming that it might have something to do with when the setting is applied. It seems like the setting is applied properly when you toggle the setting but it doesn't on the initialization of the extension. This is just my best guess though.

Before the latest update Fit to windows had stopped working on chromium browsers due to requiring use of trusted type policy, this is not required on non-chromium browsers like firefox. Latest update to the extension had fixed it for chromium browser but it does't work on firefox. I have a fix that could work but don't know how to test on firefox.

Aug 15 '24 03:08 SabalM

Checked the code, few hours ago fix has been added already.

Aug 15 '24 04:08 SabalM

alright @SabalM is there a way to add that now while I wait for next months update?

Aug 15 '24 04:08 Korygauger

It would have been easy to do on chromium browsers. I'm not sure on firefox.

Aug 15 '24 04:08 SabalM

Piggybacking off this; so do we just have to wait for the next update for the fit to window feature to work on firefox?

Aug 22 '24 15:08 junvm

by the way with the recent update fit to window is still not working due to a different error. svg is not defined.

this.createPlayerButton({
			id: 'it-fit-to-win-player-button',
			child: svg,      // <- right here
			opacity: 0.85,
			position: "right",
			onclick: function () {

this is on line 825 of player.js in the www.youtube.com directory of the repo
