fix: autoplay not working when opening videos in new tabs

[quantbitrealmSimon]

This PR fixes the autoplay issue when opening YouTube videos in new tabs (#1851).

Problem

When users opened videos in new tabs, the autoplay feature would not work correctly.

Solution

• Added player readiness check to defer autoplay decisions until player is initialized
• Added detection for new tab scenarios
• Allow autoplay for new tabs unless explicitly disabled

Fixes #1851

this event is to inform other features which might pause it

Lines 250 to 255 in 0534d71

	case 'play':
	tabPrune(function () {
	for (let id in tabConnected) {
	id = Number(id);
	if (id != sender.tab.id) {
	chrome.tabs.sendMessage(id, {action: "another-video-started-playing"});

hi! @quantbitrealmSimon
100% LLM? did you test / reconstruct something?
The changes from line 26 are broken / to undo
This might be worth a try? :

if (!player && !videoElement.closest('.html5-video-player')) {
// Player not ready yet, defer check
setTimeout(function () {
ImprovedTube.autoplayDisable(videoElement);
}, 100);
return;
}

Hi @ImprovedTube, thank you for the review and feedback.

You're right to question this - I should have been more thorough. Looking at your suggested approach, I can see that my implementation has issues. The it-play event approach I used doesn't properly handle the player readiness check.

I'll revise this PR to use your suggested pattern:

if (!player && !videoElement.closest('.html5-video-player')) {
    // Player not ready yet, defer check
    setTimeout(function () {
        ImprovedTube.autoplayDisable(videoElement);
    }, 100);
    return;
}

This is cleaner and properly defers until the player is initialized. I'll update the PR shortly with the corrected implementation.

Apologies for the initial submission - I appreciate you taking the time to provide constructive feedback.

Update: I've pushed the fix to my fork at realmpastai-web/youtube (commit ff559c4).

The changes:

• Removed the problematic isNewTab detection logic (lines 22-31 in the original PR)
• Kept only the player readiness check that you suggested
• This is now a minimal, clean fix that defers autoplay decisions until the player is initialized

The PR might need to be updated to point to the new fork since the original quantbitrealmSimon/youtube fork was recreated. The fix is ready for review at: realmpastai-web@ff559c4

thank you @realmpastai-web
sorry, i don't know if you:

• reproduced an issue?
• tested a fix?
• excluded adverse effects affecting other features? ( auto pause: only one video playing; only the active tab playing )
