I just report two problems I have with all versions above the 53 version of Opera.
I always have 130 open tabs and with the 53 version of Opera it is not a problem. But with all versions above 53, including the Beta 63 version, I always have 100% CPU occupancy, even after all tabs have been fully loaded, making the computer unusable because he is very slow. With version 53, processor occupancy normally drops when all tabs have been loaded and oscillates between 5 and 10%. I specify that I use other browsers, Chrome, Brave, Firefox, Vivaldi, but Opera is the ONLY browser that has this problem. The only solution I found to be able to continue using Opera, which is my favorite browser, is to use version 53 and disable automatic update. It works, but I wish I could use the newer versions of Opera.
It's also impossible for Opera not to load all the tabs entirely, while Firefox allows it, which speeds up the opening of the browser a lot. Firefox opens in seconds, while Opera takes more than 4 minutes and fully loads all tabs unnecessarily. Firefox only loads a tab if you click on it.
My computer is a 27-inch iMac 2011 i3 3.2 GHz with 16GB of memory with High Sierra and that works perfectly.
Thanks for your help.
Is there some feature you would love see added to Opera browser on computer? Let us know!
I know it's not a bug, but I created a issue to let this know.
This "change" is very annoying, and lot of users complain about it, so I create an issue for it.
There a a lot of explanation of why users want sidebar only in speed dial or opera pages only in the main thread in opera forum :
Main thread : https://forums.opera.com/topic/31727/side-bar-for-only-speed-dial-option-opera-60/82
Without it, flow becomes useless as we need to do a complex process to access saved flows on desktop...
I really hope this feature will be back soon,
How can I disable Auto-Update?
In Opera's installation folder (Menu > Help > About Opera for the path), find the folder with the current build and rename the auto updater executable file inside it.
Type the following into a terminal:
defaults write com.operasoftware.Opera OPDisableAutoUpdate true
Posting about your problem
After have done the steps above and confirmed that the problem is most probably in Opera, it's time to post about it.
Start the topic with a title that briefly describe the problem so people will know about what this is about.
Don't try to explain all the problem in the title.
Use tags to make it easy for other users to find posts about similar issues. If posting about Opera Mail then add the 'Opera Mail' tag
In the post (body) you should include the following information:
Your OS (Linux, Mac, Windows)
Your version of Opera
If the problem is with a page, a link to it
A screen-shot of the problem if it's related to something not showing as should
A description of the problem, including as much as information as possible
Steps to (try to) reproduce the issue

And unfortunately, it is still doing it. No update to fix it. I downloaded opera in the hopes it wouldn't become like brave or chrome or any other browser but apparently the people who have made it obviously do not seem to care.
I would recommend enabling Chrome extensions:
Then getting my extension from the Chrome store:
I had one published in Opera store but as mentioned above, it was removed.
I even tried publishing a version that doesn't change the new tab page,
but I didn't even get a response about it being reviewed or anything.
Opera extension publishing has become a nightmare ...
