If the audio you hear from the video is always from a Youtube video, check your liked videos and watch history on Youtube to see if you have any weird videos that you didn't like or watch in there. If so, you might be experiencing this issue.

@romkar I know right, I'd prefer no audio cue than this dumbass new one they added

@ayushtwry Since it has nothing to do with Synchronization, please say what OS you are using so that this topic can be moved to the correct place.

@quik Yes my system can handle it because when the animated background is loaded i can re-open a new tab and it doesn't freeze, but if i stay on the same tab for a while, when i open a new tab i have the problem again! I think they should preload the animated background at the start of OperaGX instead of at the opening of the tab! And i'll try next days without the animated background and comeback here to say if the problem persists!

@leocg I've tried workspaces when introduced in Opera.
They don't solve nothing as they keep all tabs permanently
loaded, only hide them, but they are still in memory (as seen in task manager).
Plus, not very easy when having tab active and switching, remember of problems.
Disabled completely.
As an hygiene measure anyway, I don't keep more than 20-30 max tab open, and in case of temporary crisis, I use a small extension like Tab Hamster that let me group and store tabs by argument or whatever, while removing them from memory and open tab list.

@leocg I had run an anti-virus and cleaned some other problems too but i also discovered the cause of the problem. Which is not related to the browser or at least not directly. It was a website that i am using that was having pop up ad system which normally always blocked by Opera but seems they either changed something or my Opera got lazy so it started to show itself. Added it to the adblock list as an extra measure which now closes the pop up easily. Though why it didn't before i do not know. Anyway thank you for helping me.

You have to shift back to chrome for this function because in opera it is not supported. In chrome, you can perform this task easily.

@mmnak Then the browser crashed.
