How to bookmark all open tabs in Opera 30 as a folder?

How do I bookmark all open tabs (in the current window) in Opera 30 (e.g. as a folder)? There doesn't seem to be such an option in the vanilla installation of Opera...

P.S. Add-on solutions are accepted.

It appears that I've found an Opera extension that does what I want - bookmarking all open tabs as a folder (and also offers the option to export all bookmarks as an .html), but its extension permissions are too much if you're even a bit paranoid, so stay away from it if you're concerned about your privacy:

I've tested it with Opera 30 and Opera 31.0 and it works fine.

P.S. Session Buddy (as mentioned by @ BlueBerry - Vignesh4303) is also an option, but it's more of a session manager and not a bookmarks manager. If you just need a list of all open URIs and don't like to bother saving them as bookmarks or as a browser session, you may want to check the following Opera extensions: CopyURLs or Copy URL + Title and Bulk URL Opener.

Not sure about Opera 30, but in 33 there's an option in the context menu of the tabs - "Save tabs as Speed Dial folder" - and I don't think it's a new feature. If it's there, just click it, then go to Bookmarks, navigate to the Speed Dial folder and drag the new folder elsewhere.
