Yeah, this issue appeared to me too after the last update a few days back. I also immediately checked if the settings were OK, and they were; Opera is supposed to warn me if I try to close several tabs at the same time, but it doesn't.

I found a site which suggested the following solution:

1. Launch Opera web browser and type opera://flags in addressbar and press Enter. It'll open the hidden secret advanced configuration page called "Experiments".

2. Now click inside "Search flags" text box and type warn. It'll show following option in the result:

Warn on closing browser window with multiple tabs
If enabled, browser will ask for confirmation when closing window with more than one open tab. – Mac, Windows, Linux
#warn-on-closing-multiple-tabs

3. If you want to permanently enable the new warning or confirmation message on closing multiple tabs, select "Enabled" from the drop-down box.
   If you want to permanently disable the new warning or confirmation message on closing multiple tabs so that no one can enable/disable it using Opera Settings, select "Disabled" from the drop-down box.

4. Opera will ask you to restart the browser. Click on "Relaunch now" button to restart Opera.

This solution did not solve the issue, though. But at least you now know you're not alone with your problem. Let's hope someone who knows about these issues finds this thread soon.

This exact thing happened to me today, just 10 minutes ago, and my Opera version is exactly the same.

I use the bookmarks bar, and the bookmarks are arranged in folders. Today I noticed that one of the folders had moved into another folder, making it a sub-folder. I tried to move the sub-folder back to its place in the bookmark bar, but it made Opera crash. I tried this several times unsuccessfully. Every time Opera crashed. The first times I ran Opera again, it returned to the session I was in with the tabs open, but then after a few crashes it stopped opening the tabs and I had to retrieve the pages I had read from History. On top of this Opera disabled the extensions, so I had to enable them again.

@somersgreg I was wondering about the same thing, and had to check it from some help section to find the answer.

1. In Opera 25, one cannot choose speed dial icons. Why this is, no one knows. So you cannot do that, at least yet. Maybe the developers will reintroduce the speed dial icons in the future.

2. The purpose of the "1 to 4" (it can be more too, for example "1 to 7") is to chose a picture for the bookmark section. So when you click the bookmarking heart, the page is saved into your bookmarks. Then the small drop down menu with the "1 to 4" appears and you can scroll the tiny pictures with the arrows on both sides of "1 to 4". Whichever picture you stop on, appears as the image for your bookmark. So basically this new function is a way to choose an images for your bookmark icons, in the same way as the speed dial icons previously had images.

Thanks for all the answers. I guess I needed some reassurance that I wasn't completely alone with this problem and that there are solutions to it.

But it's a known issue for some users. It's being tracked as DNA-19861. (Source)

OK, that's good to know.

I cant tell if it did that to mine, I have my only remaining thumbnail set to where you cant even see it

That's fantastic, colderwinters. I needed that

A few hours ago I updated Opera to version 21.0.1432.57 like a good boy. Now when I opened it again, all the images in my Speed Dial were missing:

Reloading the Speed Dial does not help. This is not a major problem since I can still see the titles for the Speed Dial buttons, so I can still use them, but not seeing the images on the Speed Dial buttons is annoying. (The titles on the buttons are redacted in the image above.)

What to do, what to do?

Doesn't work for me either, and at the moment I desperately need my bookmarks in Opera Link, because my last computer crashed and despite having bought a new one, I cannot for various reasons open the bookmarks that I have saved on an external hard drive. So hopefully the Link works soon so that I can access my bookmarks again.

Question:

Why doesn't the address bar show more than four previously visited addresses? In this example, when I begin writing "washingtonpost", the bar only shows four addresses, despite the fact that I've visited far more pages on that site. There is no option of scrolling down to look at more links. This applies to everything I write in the address bar; only four links to previously visited sites are shown.

I could of course use the History tab, it shows all the pages I've visited, unlike the address bar. But having the History tab open is frankly annoying. I would like to just punch in a few letters in the address bar and quickly select the correct link from the selection that appears.

Can the amount of links the address bar displays be altered somewhere? Or better yet, can a scrolling function be added to it somewhere that would allow me to look through all the links, even those hidden because of the four address limit in the bar?
