I tried a little experiment, that so far seems to be holding, only time will tell. I went to the themes folder where Opera saves the wallpapers in zip format and deleted everyone there.

The path in my case was: C:\Users\Terry\AppData\Roaming\Opera Software\Opera Stable\themes

So far I've been able to keep a background picture for two days with no problems. I'll keep your updated. As I said originally it's not a serious problem but it is annoying.

In my case I have my personal pictures on my hard drive. I drag a picture to Opera and then right click on it and click on Use image as wallpaper. Sometimes it holds sometimes it doesn't.

It's usually only effects local images not the ones built in Opera, it doesn't matter which picture. It's usually gone within a day in my case. I'm beginning to think it's just a bug that Opera has to work on. Again thanks for all the replies.

It happened to the last two pictures I used. Both where my own picture's not the ones built into Opera. It's not important enough an issue to create a new profile. Thanks anyway for the reply. I'm beginning to suspect it might have something to do with me moving the picture from it's original place on my hard drive.

You can add a background picture to your seep dial page. Opera keeps removing my background pictures. I set up a picture for the background (on opera speed dial) and eventually it will be gone. And it doesn't even show up in the Recent Wallpapers list as they normally do. It's not a serious problem but is annoying having to reset the background pic. Anybody else having this problem and is it something that can be fixed? This is on Windows 10 with the latest version of Opera and only started with this update.

I was just trying to remove this one address but I couldn't until I decided to erase the history completely. I went to opera menu, then history, then Clear browsing data and decided to check everything and give the system a good cleaning out. I'm still curious where it came from. Again thanks for the replies.

Thanks for the replies. But none of the suggestions seem to work it doesn't seem to be listed in either autofill or passwords. Ctrl+U or checking the source code reveals nothing either. It seems to happen only on one site so far so the problem might actually be a site issue. Again thanks for the replies.

So I go to a website and t asks for an email address and when I click on the field to fill it in I get a little pop down menu to use which account information I want to select. But there is an email address there and I don't have a clue who owns it. Or how it got there. So how do I get rid of this autoform fill in email? Best I can describe it.

Go to Opera's menu and click on Bookmarks and then Bookmarks again, or press Ctrl + Shift + B, or if you have the bar on the left hand side showing click on the heart shape. Then down the left hand menu, you'll see headings like Bookmarks bar, Speed Dial, Other bookmarks and before each entry is a little triangle. Click on a triangle opens the folder structure under it. They might be in the other bookmarks section and look for imported. They are probably there. You can then use Ctrl + A to select all your bookmarks at once and drag and drop them to the Speed Dial section just above Other bookmarks.

When you use that route page > save as pdf Opera seems to convert the page to a graphic and squish it all on one page, no matter how many pages the web site has. I have the same problem. Best to go the route of O > page > print > and then choose the PDF option.
