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

@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

Also this is second build in a row that crashes each time when I send a POST form. I cannot provide URL because it is locally developed site.

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

When there are a lot of opened tabs, some of which are pinned, at some point of time when tab bar scrolling is disabled and pinned tab is active, there is no possibility to switch to the tab at the end or to create a new tab because some part of the tab bar is overlapped by search icon.

Last time this happened when I clicked middle mouse button on the link being on a regular tab (that action created a new tab island) and then switched to pinned tab.

This is long lasting issue that persists since tab island was introduced or even older.

Extensions that were broken in the last build are still broken on Linux x64.
Repair button does not work.
Here is what I see at the console when press repair button:

[2223667:2223667:0201/222337.031388:ERROR:CONSOLE(0)] "Uncaught (in promise) Error: Could not fetch data from the Opera add-ons catalog", source: chrome://extensions/?menu=updates (0)

@skpy: Forgot to mention I'm on Kubuntu 22.04

I started browser by clicking on the link in my email client and unfortunately all my opened tabs from the last session was gone
