Why does opera use so much memory?

I've read some topics here, but they were locked.
In the past, i decided to download opera, and it was very light. Since last year or many months ago, i noticed that opera is kinda using much memory. For example, right now, i only have youtube opened and this tab where i'm writing, and it takes 1200 Mo, and i'm almost 50% of memory used, how is it possible?
How to fix that? I tried the extension "tab suspender" of opera, but it doesn't change anything

Opera and other Chromium browsers separate tabs into processes. And, now, for security reasons, they use strict site isolation, which creates more processes. Extensions (including built-in ones) are in separate processes too. Sidebar apps too. Flash too. GPU process too.
So, in general, running a browser is like running a boat-load of programs all at once.
Why the youtube tab is using a lot of ram though probably depends on what you were doing in that tab (What video, how long and how long you watched it etc. and a whole bunch of other things). 1.2gb of ram being used isn't really surprising these days.

For a start, see Opera's task manager to try to find out what is using the memory.
Hi, here a picture of task managers https://nsa39.casimages.com/img/2018/12/02/181202122241870330.png
And i can't access to opera tasks manager, i do right click but they don't suggest any task manager of the browser. How can I access opera's task manager?
AAah while writing, i've just been randomly in the "logo" of opera, and "developer" and i found task manager
And all those things are only 2 tabs opened right now, youtube homepage (so no video playing at all!) and just the Opera forum.
Isn't it a little much for just 2 tabs? And no video running furthermore

I see. But it is just weird (im not used to it, i only noticed it for a few weeks that Opera became kinda slow, i can hear the fan working).
In the past, it would use only like 30% of memoryYesterday, i tried mozilla firefox, even Firefox uses less memory, for the same number of tabs (3 tabs for example). And last night, i had over 10-15 tabs opened, Firefox would use upto 500-600 Mo (youtube, video, html pages, google search, google image, websites,...), while Opera uses 900 Mo for only 2 tabs (Opera forum + homepage of youtube)
It's really surprising actually ?? I don't know how firefox manages the memory, but opera used to be "lighter" than firefox (now idk but last night, i could feel a big difference :/)
