@rogue-river: not really, some of us don't actually want tab islands in the first place.
Nor do we want the obnoxious Aria icon in every single frigging text box.

Opera is going downwards fast, sadly...

@adam1709: I'm with you, Opera please #BringBackTabBarScrolling as a setting, not an experimental flag!

@stolis: No, they shoul have better testing and maybe do a rolling upgrade.

Disabling auto-update will only make people keep using old, vulnerable, outdated versions of the browser, which could be even worse than this.

I have been bitten by this bug, fortunately I had backups and could make the update work.
(I don't know why my profile from Wednesday didn't work, but my backup from Sunday allowed the update without issues, thank $DEITY)

@kmielczarczyk: Please, bring back the Recently Closed Tabs button, I already use Search in Tabs via its shortcut and I don't need a dedicated button.
Now, the Recently Closed Tabs functionallity is buried under a submenu, not user-friendly at all.

Twitter an Youtube videos are crashing on this version for me.
Anyone else?

I'm on Slackware64 Linux 15.0 RC1 (-current), KDE Plasma 5.22.4/X11

Damn, nwjs-ffmpeg-prebuilt 0.55.0 doesn't work with chromium 93, I'll try opera-beta-ffmpeg-codecs-93.0.4577.18.

That worked, thanks again @thelittlebrowserthatcould !

@ghirahim: Not sure where you are getting this but I doubt this will ever make it to the main Opera.

From https://www.opera.com/one

Opera One (currently early-access developer version) is a completely redesigned browser, planned to replace the flagship Opera Browser for Windows, macOS, and Linux later this year.

@burnout426 the version from herecura didn't work for me either, I had to revert to https://github.com/nwjs-ffmpeg-prebuilt/nwjs-ffmpeg-prebuilt/releases/tag/0.76.1 to make videos not crash Opera

#BringBackTabBarScrolling please!

@Opera-QA-Team
Hello,
The new update 125.0.5729.15 is still broken on Linux under Wayland, it crahses and won't open.

$ kinfo
Operating System: Fedora Linux 43
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.1
Kernel Version: 6.17.10-300.fc43.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 5600H with Radeon Graphics
Memory: 16 GiB of RAM (15.0 GiB usable)
Graphics Processor: AMD Radeon Graphics

Fedora KDE here, same issues as reported by others.

I downgraded manually but the broken update is still available in the repos:

$ LANG=C sudo dnf --disable-repo=\* --enable-repo=opera check-upgrade
Updating and loading repositories:
Repositories loaded.
opera-stable.x86_64 125.0.5729.12-0 opera

On Fedora KDE 43, this version of Opera Stable (124.0.5705.65) and also Beta 124.0.5705.51, fail to get focus when I click on a link in another app like kmail or akregator, i.e. the website opens but the browser remains out of focus.

Previous Stable didn't show this behaviour, neither did previous versions of Beta.

There's also another issue that Opera Stable and Beta recieve the Alt key in some circumstances. At first I though it was a problem of XWayland apps but it keeps happening with Opera working native Wayland (--ozone-platform=wayland).

Repro: open Opera, open Konsole, Alt+Tab to Opera, Alt+Tab to Konsole, use Alt+F4 to close Konsole, Opera recieves the Alt key and opens its menu.

Operating System: Fedora Linux 43
KDE Plasma Version: 6.5.3

Qt Version: 6.10.1

You should provide the update in the RPM repos to be more effective:

Available packages
opera-stable.x86_64     123.0.5669.47-0     opera

"Please note that a Linux build is unavailable for this release"

I'm kinda relieved and hope it's because you're trying to fix this annoying bug I reported on 124 Beta release:

Hi!

I'm on Fedora 43 KDE Plasma, just upgraded to Opera Beta 124.0.5705.12.

The Opera window won't come to the front when I click a URL in another app, like Akregator (RSS reader).

Previous version did.
Regression?

Hello,

I was using Opera Beta and opened a lot of tabs, unfortunately it's a website that somehow made Opera use a lot of memory and it got killed by the OOM killer.

After reopenning Opera, only 2 of my 4 windows got restored, with no way of restoring them, nor any traces of the lost tabs in the history.

I only have a backup from last Sunday (6 days ago).
Is there any way to recover all those tabs from Opera itself or should I consider them forever lost and restore from the backup?

Browser info (translated from Spanish):

Opera One (version: 121.0.5600.12)
Updates channel :beta
System: Fedora Linux 42 (KDE Plasma Desktop Edition) (x86_64; KDE)
Chromium Version :137.0.7151.27

Hi @marinaz909

I don't know what changed exactly but after updating to Opera Beta 120.0.5543.29, Privacy Badger started working normaly in every site I tried.

Hi @marinaz909, sorry I haven't been able to make some time for this.

I do have several extensions active:

• Opera's ad blocker: Version 120.0.5543.12
• JSON Lite: Version 20.10.1 by lauri-rooden
• Privacy Badger: Version 2025.5.30 by efforg
• Reload Images: Version 2.5.2 by mubaidr
• RSS Detector: Version 2.0.2 by BS-Harou (Martin Kadlec)
• YouTube No Buffer - Stop Auto-playing: Version 0.4.6 by james-fray

I don't think I'll be able to test in the next few days, maybe next weekend.

I'll get back to you with my results.

Thanks again!

@marinaz909: Thank you!
