@Gwen-Dragon This is the link to update the Media Feature Pack in case anybody needs https://www.microsoft.com/en-us/software-download/mediafeaturepack.

I thank you greatly. Yes, I have Windows N and this is the solution. Important, restart windows after the adding of the Media Feature Pack.

@Pathduck Thanks for responding to my issue. The problem is solved! The media features for windows N. I apreciate a lot your time and effort. Have a nice day.

There were issues in Win10 with HEVC. MS was to have provided a fix but I didn't get it (?!). Still running Windows 10 OS Version 1909 (Build 18363.900) so I had to uninstall HEVC. Not sure if our issues are related... I don't think this affect V that way, these are just outdated CODECs.

Pettern seems to be correct. MS upgraded my X64 Windows 10 Enterprise N to Version 10.0.19041 Build 19041 last night, and this morning Vivaldi went to the pale V splash screen and then disappeared without trace. Several times. So then I upgraded Vivaldi to the latest version , and as egigoka put it so well: Steps: Install Vivaldi 3.1+ Try to open Expected behavior: browser opens Experienced behavior: opens windows with Vivaldi logo and no interface for couple of seconds and closes... After searching for a while here, I realised that it HAD to relate to something of MS's upgrade, and went looking there (Technet) , to discover that Win 10 N versions do not include the Media Feature Pack; it has to be installed separately. So I did, and Vivaldi is back! Thank you all. Posting this in the hope that it will help others to a speedier resolution... Note that other than installing the latest version, I have done nothing to Vivaldi itself. currently Vivaldi 3.1.1929.45 (Stable channel) (64-bit) Revision 1eb3263017ed42270818939fbff241845938a81f OS Windows 10 OS Version 2004 (Build 19041.388) JavaScript V8 8.3.110.13

I can't find the "renitent" button. I installed all extensions, that were installed on the wrong instance of Vivaldi. But Youzeek works. (Although breaks playing frequently.) But I detected an other problem with extensions. I use Extension toggle to hide the hidden buttons in the earlier installed instance. The showed buttons are out of the Extension toggle. But if I install clean the same build, and import the same extensions, and I activate the Extension toggle, then I can't show the buttons. In the clean installed instance I haven't right click menu item as Show button/Hide button. All extension are hidden, and I can pack and unpack only the all extensions together.

@Linu74 Nope.. not for what I need I don't. Just fixed the issue, and loading the test page, the browser now plays H264 and HTML5 - which is all I need really for Youtube etc. I have a media player for music, and I don't do streaming or such. So, it works for me now and, importantly NO external packages.

@iAN-CooG said in Automatically un-mute tabs that were playing when using "Prioritize active tab" option: As for now, you can set keyboard shortcuts to quickly mute all other tabs than the currently active one, and unmute all tabs, so it's just a matter of learning to press a key whenever you need it. You can certainly set keyboard shortcuts or mouse gestures to unmute all tabs. But it doesn't work if there are more than one windows open. When I play spotify in one window and I have sound going on in another window, spotify stays muted. Doesn't matter if I try via mouse gestures or keyboard shortcut. I have to open the window with the spotify tab in order to get the gestures/shortcuts to work. As I said before, if the devs just didn't fuck around with the Prioritize Active Tab all of those issues would be resolved. I mean, the option even implies some sort of ranking order in which sound is muted/played, not just a simple on/off.

@GastonMACOUTE Désolée pour ces soucis et de te savoir si enragé. Afin de pouvoir t'aider, nous avons besoin d'en savoir plus. Comme les autres l'ont mentionné nous avons besoin de connaître: le système d'exploitation que tu utilises, sa version ainsi que la version de Vivaldi. Aussi as-tu déjà envoyé un rapport de bug? Si oui, quel est le numéro afin que nous puissions le suivre en interne? A bientôt? 🙂

Is this "Silver Mac Pro" in common?

I wholeheartedly agree with this feature. I use PiP regularly and being able to see subtitles on it when they are available in the original player would be extremely helpful.

@zeiglerxz That is a great idea! The android smartphone has a similar feature: When it's playing music, the usual set of buttons (previous song, stop, next song) is displayed on the lock screen and on the notification bar (I don't know what it's called). On the web browser, I'm often annoyed by how cumbersome it is to stop the sound from a tab when I have many tabs: Brows the tabbar to determine which tab is making the sound. Activate the tab and hit the stop button. You could say that I could hit the loud-speaker icon on the tab instead of step 2, but that would just shut the sound up without stopping the playing, which wastes some CPU resource.

@zdm Unfortunately, you can't set this as a default style. You could add it to it's own file under resources/vivaldi/user_files, then every time you come across this, open page actions and turn it on.

@gwen-dragon They made a feature request thread, some moderator moved it. Just move it back, I already upvoted hours ago.

Hello, sorry for the late reply! It could be an option, if the buttons are easy to click (even with 50 tabs open ^^). But I see two advantages with the "OS" solution : if you listen music as background, you don't have to open Vivaldi (for example if you are on a text editor). it doesn't take place in the tab bar. After, both solution could be used simultaneously. Just an idea 🙂

I would really like this feature. I would have a ton of websites in the Web Panel if they were persistent across all my windows. As a multi-window user, the current limitation makes the Web Panels nearly useless for me.

@gaelle But how about accepting that we post in apparently wrong groups, and try to read through is all carefully and consider if just posting the bug / problem he suggest that something else is wrong. That what you believe the problem to be stems from not fully understanding the problem. I have had the request moved and deleted, and bluntly, I know the problem and can fix the code - but I have to repeat the "fix" every time I receive a new version of Vivaldi. Yes - I have posted the fix. I don´t know it it fixes it all. I got my video working, but still get the "wrong codec" - and sometime I know the reason. Where to place it - how to report? Very good question. It is not really video you see.
