@burnout426 You make fair points. But the "recently closed" menu contains only the last 25 closed tabs, and is therefore not always enough, not if one accidentally closes, say, 50 tabs. The "Reopen last closed tab" function which I used is the one that opens the 25 tabs in the "recently closed" menu.

@anonan I agree, my behaviour is both funny and pathetic at the same time, but the menu route is just something I got really used to before I learned the hot key command, and it's been difficult to unlearn, and it's convenient when only using the mouse to navigate, without the second hand on the keyboard.

But the main reason for going the menu route is that even though I try to use the X button on the tabs as often as possible, most of the time I want to close background tabs, not the one that is active in front of me. And only the active one has an X button, the background tabs do not. So it's easier to just right click on a background tab, and choose "close tab".

But from now on I'll certainly try to unlearn by bad habit and get over my addiction to the context menu. I'll have to start using the mouse wheel technique which I did not know of until your reply.

Opera has placed the "close other tabs" feature right below the "close tab" feature. That's as dangerous as placing a nuclear warhead launch button right beside the light switch in your room. These features being beside each other makes it very likely that one ends up closing all other tabs instead of closing the one tab that one intends to close. This is made worse by the fact that Opera does not have a functioning way to recover accidentally closed tabs; there's no clear list of tabs that were previously open, no way to easily get them back with a click of a button.

So please, hide the "close other tabs" function so that it's far away from the "close tab" function. I'm sure the former function is sometimes useful to some people, but not so useful that it needs to be visible all the time, especially right beneath the "close tab" function. The risk for a mis-click is far too big.

An other option is to add an "undo close other tabs" function, so that in case one accidentally closes them all, with a click of a button one can have them all back. An alternative to this, yet a less practical one, is that you add a warning window which pops up any time one tries to "close other tabs". This shouldn't be difficult since you've already given the user the option to choose if a warning window pops up when one is trying to close Opera.

A third option is that you simply introduce the feature which people have been wanting for years: a clear, easy-to-read list of the previous tabs that were open before they were closed. The "Last Session" and "Last Tabs" files in the "Opera Stable" folder are no good. They are a jumble of symbols and letters which one has to spend hours interpreting to find the web addresses in them, and even after all that work one doesn't really trust that all the addresses for the tabs one accidentally closed are in these files.

The "history" tab is also useless because it only displays the most recent tabs that have been open. If one accidentally clicks "close other tabs" in a window with several tabs that have been open for months, these old tabs will not be in the page history.

I'm a big fan of the "warn on quitting Opera with multiple tabs open" function. It has saved me several times already. But the fact that one can lose all but one of the tabs that are open, just because one accidentally clicks "close other tabs" instead of "close tab", and there's no way to reverse this with an undo function, is really infuriating.

Half an hour ago I lost around 60 important tabs that way. A sizeable number of them were so old that I can't find them in the History list. The "Reopen last closed tab" only opened around 15 of them, and they were the newer tabs. Now I will have to start sifting through the "Last Tabs" file to see if I can find the addresses I lost. Not something one wants to do when busy with other more important things.

@gamalaptop Yes, now it works again, thanks to the recent update. The issue is resolved. But when I posted my original comment it didn't work.

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.
