Is there any possibility to back to old behaviour of this function via settings?

I am not sure if it is web page issue or I found memory leak which consumes whole RAM until my PC (Windows 7 64-bit become unresponsive). Can somebody please confirm that? The problem occurs on the following page:

PS. Ads blocking was disabled in my case, otherwise this page will not display properly.

@domovnik: Fully agree with you.

Looks like you've broken FTP handling. FTP pages are blank.

@johnd78: Thanks bro!

Is there any way to disable the new extra window showing thumbnails when trying to upload files?

In this version there is next 2 things broken: 1) ctrl+g doesn't work anymore (so far it was functioning as ctrl+f of a last searched phrase), 2) after writing web URL or search phrase in URL bar and pressing displayed (prompted) address using left mouse button (my enter key doesn't work so I don't know how it works when pressing enter), given page starts to load and then opera goes back to speed dial page.

BTW, Opera has a bug in URL bar list which annoys me quite a bit when I'm using browser a little bit faster. When you click the URL bar, the addresses from history and prompts appear and then, when you hover over the list, then you have to sometimes hover over multiple times as at first it doesn't recognize properly the position of cursor and highlights bad addressess.

I also think that the green padlock was way better as you could quickly check if given page is secure (I know that in fact that's simplification but still way better). And the protocol prefix (like http/https) displaying was also nice.

Your idea is good if only it will be possible to disable these shortcuts in settings. With the URL there are other things to improve. 1) When I'm typing, it prompts random previous pages from history even though in history there are exact web pages' titles and addresses which are more relevant. 2) Maybe it would be better to list more results from history and google prompts or allow us to set limit of number of lines. 3) I'd love to see better prompts from google. At the moment google prompts whole passphrases even though many often times I want to enter single word. So prompting one word at a time (the first words of a whole google prompt) would be some relief when searching.

URL bar has buggy writings sometimes.

It seems to me that Opera adds bookmarks (at least to the speed dial folder) randomly. All the bookmarks I mentioned are pages I visited earlier.

@leocg: I found that this bug also disappears (besides browser restart) after new window opening but not the new private one.
