For those of you who are not satisfied with new Opera: try Otter Browser (Otter Browser aims to recreate the best aspects of the classic Opera [12.x] UI using Qt5)

@someonepl,
You say, "Let's say I want to reopen a tab closed before 5 other tabs. Do I have to reopen 6 tabs? With keyboard? I would like to do it with a mouse." Click on the menu with your mouse (top left of browser) (or open it with Alt key or Alt F) and scroll down to Recent Tabs, 5 down from the top in my version. Then select with the mouse "Recent tabs" and chose the one that you want to open, the one that is that you closed before you closed five other tabs. That's simple to do with the mouse.

OK, I got it. Three clicks instead of two + not so comfy like an old trash can, but maybe I'll get used to it.

Without SimpleUndoClose add-on I just had to install it's 50 % worse...

So, you need an addon to do a function that is already in Opera? Why? Ctrl+Shift+T reopens the last closed tab. In addition soon to be released updates add recently closed history to the tab bar (similar to the trachcan of older releases). Even without that you can see your recently closed history in the Opera menu in the current version.

Let's say I want to reopen a tab closed before 5 other tabs. Do I have to reopen 6 tabs? With keyboard? I would like to do it with a mouse. I hope they will add trash can soon.

a browser with worse interface than Opera had many years ago.

As I said above it took 18 years to make Opera what it was. What do you do for a living? Do you think you could perform 18 years worth of whatever your job is in 2 years? Talk about unreasonable expectations...

But that job is done. It just needs to be implemented. 2 years is enough. I'm not a developer, but, I think, they make much more sophisticated software (from scratch) than, for example, "recently closed tabs" function out there.

They just got rid of the old Opera, and named Chrome Opera 15, and this is strange. They should keep developing until (at least) implementing most important old functionalities, and then release new Opera IMHO (with new engine, of course).

I hope all old functionalities will be back in newer versions (including right click+scroll)

opera is perhaps 20 % worse than what it was 3 years ago.

Without SimpleUndoClose add-on I just had to install it's 50 % worse... Bookmarks, no private tabs (only windows), possibilities of customization, and so on - almost everything is worse... I couldn't believe they decided to make Opera just a skin to Chrome - a browser with worse interface than Opera had many years ago. Make new Opera like version 12, but with new engine. No many reasons to use new version any more, really.

Greetings from Poland, where an old Opera gained pretty big share of market.

I know, but is there any way to manually put flash files (from different computer, for example) into other directory than windows/system32, and let Opera know where they are?

Hi,
Is there a possibility of installing Flash Player without Windows XP admin permissions in Opera 28?

Thanks in advance for any replies.
