So completely random then?

If you do a google search in the address bar, then click one of the links, then press back, Opera goes all the way back to the speed dial instead of the search results.

This seems to happen randomly, although one which always works is: do a search for Peter Hucker. Click the IMDB entry. Now click back.

I often paste a word or phrase into Opera's address bar, then press enter. It might be a word I want to look up in a dictionary, or a place I want to find on a map. In any case I want to use the Google search function on that word or phrase. But I tend to press enter before I've released the ctrl key, and ctrl-enter appears to add .com to the end of the word and try to go to a non-existant address. I've looked through the keyboard shortcuts and can't find this function. Where is it?

I have spam filters for email, I have a filter for people I've killfiled in newsgroups, but how do I make the messages actually get deleted automatically so they're not still sat there in a folder tempting me to look at them?

Mine plays ok in either version of Youtube, and I'm using Adblock, Adblockplus, and Tampermonkey. It's just making a new comment I can't do. Replying to an existing comment works though.

I'm unable to post a NEW comment with the new Youtube design in Opera. I can only reply to existing comments. The new comment box is just missing.

Of course it's a bug, it's a missing obvious feature every other browser has.

The prediction service works fine in the drop down below where you're typing. There's no reason to place any of it into the address bar until you click it.

I tried your example, but couldn't reproduce it. I went to xe.com to start with, so the address was loaded into it's predictor. Then I typed xegbp. The xe made .com appear, but the gbp simply wrote over it. I only experience the problem if I type nothing after what it thinks might be an address.

I just tried it with several random words, and only a few are doing it. Although the ones that I've seen it do it with in the past were sites I'd never heard of before - I can't explain that at all. Besides which, it's a very stupid idea to be adding stuff to what I type or paste without my permission. For example, if I paste (or even type) "google" into the address bar, it autocompletes it not even to google.com, but to the last thing I looked at on there - my last search. The chances of that being what I want are second to none. It should offer me this link in the dropdown box, not add it as I type so I've got to delete it.

I've tried switching off "Use a prediction service to help complete searches and URLs typed in the address bar" in the section you suggested, and even restarted Opera and confirmed the setting stuck. But it ignored me. Typing google ina fresh tab takes me to my last search. This is exceedingly annoying and they need to fix it.
