@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)

@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...

@Mlipka thanks, I searched the web and forums but couldn't find how to properly report it (and I was sure there was a way).

@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.

@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!

@weilan: agreed, the waste of space was the first thing I noticed, even comparing against Opera Stable/Beta

@aciba there are several complains on several different posts.

I'm trying to relay the message from the developers but I can only make one post every 2 minutes

The culprit Is the "Acceptable Ads" feature:

Disabling it and leaving the Ad Blocker on keeps websites working.

@JeanDXD try disablinng the ad blocker, there seems to be a problem with some blocklistt

Edit: according to https://forums.opera.com/post/409354 the problem is "Acceptable Ads" so try disabling that instead of the full Ad Blocker.

Downgraded to the previous version downloading it from https://get.opera.com/ftp/pub/opera/desktop/135.0.5973.123/linux/

But I have another similar machine with that version and now that I check there, it's still broken.

So it seems it's not the new version but some broken blocklist

Example website, notice the "12 ads blocked" message in the popup:

Hello,

This morning I received an update for Opera Stable 135.0.5973.133.

After an hour or so, I started getting random websites displaying broken, DevTools shows the ad blocker seems to be blocking some css and images.

I tried updating the lists but it's still the same, if I disable the ad blocker the website loads fine.

This is on Fedora Linux KDE 44, official Opera rpm package.
