New tabs area design looks awful. Now there is a mess when many tabs are opened.
Also why there is so much empty space above tabs?

It is still not possible to update extensions. Confirmation window messages are broken and nothing happens when clicking on Update button

Here is the same thing as with my last post: last 3 error messages appear at browser close event. I didn't sing in to my opera account so sync is disabled. Never mind handshake errors - I use self-signed SSL certs for local development.

There are 2 issues:

1. When there are a lot of tabs of the same site and one of them are playing audio - it is not possible to select the tab - the popup covers the tab under the mouse cursor and I can only add a tab icon instead of select a tab.
2. When a new modal window is opened (in this case the window to login into Opera's forum), the window bar is totally black with no buttons on it.
   

I am on Kubuntu 24.04, KDE Plasma 5.27.12, Opera 135.0.5973.133

Opera One(121.0.5581.0)
Ubuntu 24.04.2 LTS (x86_64; KDE)
Still facing an issue where all cookies are deleted when browser is closed (option to delete cookies on exit in the settings is disabled so it is not the reason).
I tried to clear cookies and other sites data for all time period but that did not help.

Also Password Manager is not saving passwords. Actually the same thing here - each time when browser is restarted, it asks to save password again and not offers already saved passwords. So form auto-completion data is saved, but passwords are not.

Here is my output when I launch opera from terminal:

The touch_communication.js errors appears at the browser closing event. So I suppose it could be related to the errors because this script communicates with Opera servers.

Please let me know if I can provide more information for my case

Each time I close the browser and open it again - all my cookies are gone and I need to login on all sites again.
Opera One(121.0.5558.0)
Ubuntu 24.04.2 LTS (x86_64; KDE)

Is there a reason why all cookies have been lost after this upgrade? I had to login everywhere again, including Opera account to resume browser sync. Kubuntu 24.04

@daria19 Just found that this issue also affects Google Docs

@daria19 I am on Kubuntu 24.04. On Opera Stable everything is okay.
Currently I upgraded to 119.0.5482.0 build and the issue still persist.
But I found something interesting:
If I change for #specs-list td font-weight to something greater than 500 or change font-style to oblique or italic then text became readable.
For now I see this bug only at this specific site.

Also the font is broken at GSM Arena comparison page

Still crashes on form submit CrashID=bp-78deb87d-3a92-4361-b963-4443d0250324
Actually the post data was successfully submitted, but the application crashed when it received a 302 status code in response.

@daria19 for some reason report for that specific crash was not saved there. But here is a new one for the same issue: CrashID=bp-acc79ef2-03fe-4def-b194-9a5e70250322
