1880701 - YouTube shortcut navigation issue, when CTRL-tabbing between tabs Firefox is not longer focuses on the vid.

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Joseph DeVore]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:122.0) Gecko/20100101 Firefox/122.0

Steps to reproduce:

1. open a new tab to YouTube.com and start playing any YouTube video.
   ctrl-tab to another open tab or website and back.
   example vid:
   https://www.youtube.com/watch?v=auAYd1EN3jY

Actual results:

the playback shortcut of using the [space-bar] to pause and play the video is no longer focused on the video and/or only causes the mouse cursor to appear if above hovering over the video and the display of the seekbar and controls..

Expected results:

[CTRL-TAB] should remained focused on the the video so play back can be paused or UN-paused using the [space-bar].

this has been happening since the release of Firefox v119.0 as I recall it started to happen then, unless Google changed the webpage code for YouTube again lol..

I am running Windows 11 Pro and 64bit Firefox v122.0.1
if any more info is needed or I missed something please ask.
this has been bugging me for a while lol.

hmm the other navigation shortcuts like 'F' key for full-screen mode still works..
its just the shortcut using the space-bar that isn't working right when CTRL-tabbing between tabs..
clicking on the tab using the mouse cursor, the space-bar works fine as long as the video pause was on focus..
ie.. I had previously clicked on the middle of the video or so with the mouse cursor..

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I tried disabling TabMixPlus which is an bootstrap tab addon that works in newer firefox versions thx to a good team.
and its still happening.. so that addon is not causing the issue.
and TabMixPlus is able to run thanks to a rebuild of that old XUL functionality via a custom script.

Hi, it has been about a week, so any luck fixing this issue yet?

This appears to be an old regression, not sure the author is active anymore. :jimm do you think you could you set a priority/severity on this?

I just installed the Firefox Nightly (v125.0.0_alpha01)
trying out YouTube ctrl-tabing now..
I copied my profile into the new nightly profile folder so I would have access to all things..
will report back soon.

This issue still happens on the nightly build (v125.0.0_alpha01) but I will continue to test as new nightlies come out.

I tried disabling the addon uBlockOrigin to test if that was interfering..
issue still occurs with it off.

In the regression window, Bug 1692303 - Flip default value to browser.ctrlTab.recentlyUsedOrder to false r=mstriemer,mconley,preferences-reviewers(In reply to Alice0775 White from comment #6) seems related.

Hi Mark, does this ring any bell?

Hi Joseph, Thanks for the report. I can reproduce this. When I use the mouse to click and switch between tabs, the space key works as expected, but it does not when I am using the ctrl-tab key.

BTW, in both cases, neither focus nor focusout event is observed in the video element by adding the following code in the Web Console:

const videos = document.getElementsByTagName("video");
videos[0].addEventListener("focus", (event) => { console.log("focus"); });
videos[0].addEventListener("focusout", (event) => { console.log("focusout"); });

C.M.Chang, good to hear.

I am moving this to the tabbed browser module to do further investigation.

Wonfix for Firefox v124?
sad and the issue is still occurring with today's nightly (v125.0a1)(2024-03-17)
btw I have the nightly installed along side the release channel build.

Comment 17

[Joseph DeVore]

hmm... :(
Has no one worked on this at all?
I see its not fixed as of the nightly build for 03-30-2024 for (v126.0a1)...
This bug/regression is driving me nutz.
please fix it.

[Joseph DeVore]

ooh my this sucks, still no updates?
I rely on this feature that has regressed, every day..

I updated to the latest Nvidia display driver yesterday I think.. v555.99 from v555.85 and this issue seems to have cleared up..
ctrl-tab and pausing the YouTube videos seems to be working again..
so unless Mozilla fixed something the driver update fixed it instead.. or maybe YouTube itself had a fix..??
this can be closed for now. I guess.
